The assumption that police corruption is wrong or a problem to be combatted is often taken for granted in many discussions or analyses of the topic. Perhaps this is due to the fact that the term "corruption" is not neutral, that its connotation of "moral perversion" or "depravity"1 implies that anything labelled corrupt must just inherently be "bad" and is not to be tolerated. Thus, there is sometimes little attention paid to what is wrong with corrupt acts. However, a reliance on a moral view of corruption which just assumes it to be bad can lead to an inadequate understanding of the problem. Especially when corruption seems to be quite widespread and an almost accepted part of some "sub-cultures", unless we articulate exactly what is wrong with it, some people may wonder why it needs to be combatted at all and if it is not better to just ignore it.2

This paper seeks to identify the major effects of corrupt acts on the criminal justice system, police relations with the public and the organisational culture of the police. It will emphasise the "civic morality"3 side of police corruption, i.e., the social harm that corrupt acts result in. The primary purpose of this discussion is to combat the view of police corruption as "victimless". It seeks to bring to the attention of the reader the very damaging effects of corrupt acts and to point out that such acts not only have indirect consequences, but often identifiable victims.

Before outlining some of the major effects of police corruption, it is important to have some idea of what is being referred to by the term "police corruption". Thus, this paper starts by defining police corruption. After that, the effects of corruption are divided into two sections: first, those that have more easily identifiable victims and second, those whose effects need to be viewed in a broader context. Where appropriate, examples of corrupt acts are provided to illustrate the points being made. This is not meant to imply that either the effects of police corruption are always easily distinguishable from each other or that each corrupt act has only one effect. Rather, this exercise is an attempt to broadly outline some of the major effects of corrupt acts and identify some of the practices most strongly related to specific effects.

The definition of police corruption used in this paper is the following:

Thus, to be considered corrupt, an act:

Must be a violation of South African criminal or civil law or qualify as misconduct under the SAPS or traffic officers regulations.4

Must use either the legal or organisational powers of the police. That is, in committing the act, a police officer needs to have made use of some form of knowledge, access, credibility or legal or other power available to her/him by virtue of her/him being a member of the police service.

Must be motivated by the desire to achieve some identifiable personal, group or organisational benefit or reward.

An officer not arresting someone for possession of dagga in return for some money would be an example of a corrupt act using legal police powers (i.e., the discretionary power of non- enforcement). An example of organisational powers being used would be an officer using her/his access to police records to steal and destroy a case docket in return for payment of some sort. In addition, if the officer destroyed the docket of a case where a friend or family member was the defendant, it would also be an example of corruption, as the benefit of helping someone close to you is clearly identifiable. Finally, a police commander ordering her/his officers not to investigate the alleged criminal activities of a politician who is influential and friendly towards the police is also acting corruptly, since there is a benefit to the organisation in terms of continued support from the politician.

It should be noted that there are some "improper" or questionable police practices and forms of misconduct that are not necessarily forms of corruption. One example would be an officer acting in a racist or prejudicial manner towards an alleged offender, perhaps by being discourteous or perhaps by other, more overt means (eg. using unnecessary force). Since it is difficult to identify any tangible gain for the officer involved, such an act would not be defined as corrupt in terms of the definition being used here. However, it needs to be recognised that such actions are still problematic - and may even be crimes - and that they may have the same effects as forms of police corruption. Also, such behaviour may still be viewed by some people as "corrupt". Thus, in the following analysis of effects, where especially appropriate or relevant, practices other than those formally defined as corrupt are also identified and discussed.

What the effects in this section have in common is that they often entail an identifiable person or group of people being harmed and are quite closely connected with the actual operation of the criminal justice system. In fact, they usually result in either the perversion, obstruction or diversion of the aims of justice. Also included in this group are practices which serve to divert police resources towards a particular group, and therefore potentially increase the vulnerability of other individuals, or groups, to crime. As such, the types of corruption looked at in this section often have the most obviously detrimental impact. However, it may not always be the case that a person committing some of the corrupt acts discussed here will concern her/himself with the very direct and dire consequences of her/his actions.

There are a few different ways in which corrupt acts committed by the police result in direct forms of victimisation. One obvious way is when the powers available to police officers are used in committing crimes that have direct victims. One example of this is outright stealing from individuals and businesses. This usually entails officers using their access to certain areas, such as unlocked shops, crime scenes or vehicle compounds, to help themselves to various goods. Officers have also been known to collude with professional criminals in operations such as car hijacking rings. Such cases, as Gauteng anti-corruption unit (ACU) Senior Superintendent Adrian Eager points out, are "particularly perturbing as some of [the] vehicles are obtained" by methods "which could involve murder."5 In such a case, police officers need to realize that they are not just using their powers to rob people, but, by giving police assistance to these operations, are also guilty of complicity in the assault and sometimes murder of the car owners. Another example where officers are only one step removed from the shooting or killing of people is when they sell firearms from police storage or when they rent out their own issue for a brief period.6

Another form of victimisation relates to the investigation of cases and the securing or providing of evidence. When police officers use "illegitimate methods" - such as lying about the circumstances surrounding an arrest or tampering with evidence - simply in order to secure convictions and falsely enhance their performance it must be viewed as corrupt. (In circumstances where such illegitimate methods are used in building cases against legitimate suspects, the use of such methods is still an offense; but since it is no longer motivated by personal gain, it is not, according to the definition being used, corrupt.) Such actions may result in the unlawful arrest or conviction of possibly innocent defendants. An example is the case of the junior examiner in the Western Cape who allegedly mismatched numerous fingerprints in order to provide "favours" for detectives, by helping them to falsely "build stronger cases."7 Another instance is what is referred to as "verballing" among police officers in Queensland, Australia - when the police corroborate earlier falsifications or fraudulently strengthen the case against the defendant by lying in court , knowing that their credibility as officers will give their testimony more weight than that of the accused.8

There are other cases of perjury that are forms of corruption and result in direct victimisation. As mentioned earlier, even though racist or brutal acts committed by police officers are usually not, strictly speaking, forms of corruption (as they result in no obvious gain), they are instances of victimisation. Thus, when an officer covers up for such behaviour by committing perjury, such as by claiming that the victim resisted arrest or was abusing the officer, it is not only a corrupt act (as the officer is gaining by avoiding personal harm), it is also a part of the victimisation process.

The practice of receiving kickbacks is one that is often viewed as victimless. However, besides the fact that certain businesses or people are not given a fair chance to compete for work, kickbacks can also have other, very direct victims. One type of kickback, discussed by James Morton in his look at police corruption in Britain, was when police officers in London would use their considerable "influence over the distribution of legal aid work" to direct cases to specific lawyers, in return for money or other payment or favours. One result of this practice was that lawyers had to be wary of offending, or being "hostile" to the police, and make sure that they "let the police officers down lightly if there were discrepancies in their evidence." In one instance, a "young solicitor who had given the police a hard time whilst defending and obtained an acquittal" was told by a senior partner that "he had received a call from a senior officer reminding him that the firm also relied on the police for their prosecution work."9 In effect, their ability to effectively do their job was compromised, with their clients, the defendants, being victimised. Also, kickbacks that officers receive from businesses such as towing operations or car garages can also lead to victimisation, with officers seeking, or even manufacturing, violations to enforce for the sole purpose of making corrupt funds One example, also from Morton's study, was of officers seeking out and citing vehicle owners for infractions such as driving with worn out tyres and, rather than handing out fines, giving them warnings and directing them to "a co-operative garage", one that gave the police regular payments.10

The extortion of money by police officers is also an overt form of victimisation. Here, police powers of enforcement or police authority may be used in committing a corrupt act. One example of this is the allegation that some police officers in the US Virgin Islands "routinely shake down prostitutes" and "illegal aliens", extorting money from them "by threatening to turn them in to the Immigration and Naturalization Service."11 A South African example of extortion was an incident where five officers used their police authority in allegedly falsely informing a man that "his vehicle had been used in a crime and would have to be confiscated", seizing his car and demanding R6000 for its return.12 Also, when officers refuse to do their jobs, or suggest that certain tasks will not be done, or done properly, unless the person needing police assistance "greases the wheel", they are certainly victimising the hapless citizen.

One final instance of direct victimisation is the case of police officers siding with, and often providing police powers to, "favoured" people or businesses, usually ones that provide some goods (eg. free meals, drinks), when they are in conflict with other citizens. There are reported cases of, for instance, police officers serving, in effect, as security or bouncers for businesses like pubs or restaurants and helping such establishments "take care" of troublesome customers.13 In such cases, it is clear that such customers are being victimised with the police taking a particular side rather than acting in terms of the principles of law enforcement.

"Fostering impunity" here refers to those situations when corrupt acts committed by police officers serve to provide those who have violated the law with immunity against having the law properly enforced against them. This occurs when perpetrators of specific criminal acts are able to receive lighter punishments, or avoid punishment altogether, for their crimes. In assisting such perpetrators, police officers obstruct the criminal justice process and contribute to further injustice done to the victim. Such practices should therefore be understood as amounting to a form of secondary victimisation.14 Reports of police commanders interfering in investigations, to the point of travelling to other jurisdictions to have cases against powerful criminals quashed, are instances of this type of secondary victimisation. Also, every time an officer sells or destroys a docket, s/he has become an accessory to the crime (which could be murder) allegedly committed in that case. The same goes for those who assisted in the escape of Josiaha Rabotapi, a man "wanted in connection with 16 murders and 13 armed robberies."15 Finally, a more subtle way of helping offenders escape the consequences of their acts is for officers to "make a bad case", one that they know the defence can exploit, or to intentionally perform in court in such a way as to help the defendant's case.16

In connection with the above forms of obstruction of justice, a further consequence of this fostering of impunity is the damage it does to other police officers' morale. When officers committed to catching perpetrators and solving cases see their work undone time and again by other officers, it cannot but have devastating consequences for morale. Even if officers are unaware that it is other police officers who are undermining their work, simply witnessing the neutralisation of their efforts can lead to considerable frustration and despair. As one victim of a car hijacking put it when the alleged perpetrators was set free soon after "quick detective work" had led to their apprehension: "the detectives were very excited about the bust. I feel sorry for officers who had worked so hard to catch these guys, but how can you lose high-priority criminals like that?"17

A further form of fostering impunity is when police protection of offenders becomes more regular or systematic. Often, such corruption is linked with organised crime rings such as drug syndicates. Here, the fostering of impunity has at least two major effects. First, it allows drug traffickers (or car hijackers or firearms smugglers) to consistently evade law enforcement and thus more effectively run their operations. Thus, police officers are directly complicit in the devastating harm that drug trafficking (or other organised criminal activity) causes a community and its members. Second, it is certainly not unknown for those who deal in drugs to be engaged in other criminal activity, often in the course of running their business, such as racketeering, armed robberies and murder. By allowing these criminals to remain at large and by giving them the message that they are immune from being brought to book, corrupt officers are actively facilitating the committing of these crimes. In Latin American countries such as Colombia, Bolivia and Peru, where such police collusion with drug cartels is believed to be rife, it can reach the stage where the criminals are viewed as "more powerful than government". Here, the consequence of fostering impunity is "that the drug barons are not simply above the law - they are a law unto themselves."18

Of course, granting immunity through corrupt acts is not limited to police interactions with those commonly perceived as serious criminals. A less obvious, seemingly more benign or even innocent case would be traffic officers who solicit or take bribes for not enforcing traffic violations such as speeding. Such corruption may be justified or rationalised away as not having a victim or any negative consequences, yet it is a perfect illustration of the negative consequences of corrupt acts which foster impunity. The fact is, every time it is done, it contributes to a culture of lawlessness on the road, or at least an attitude that the laws need not be taken seriously. However such laws exist for a reason - to ensure road safety. If they can be flouted with relative ease, it contributes to a decreased level of respect for the rules of the road and may lead to an increase in hazardous driving and traffic accidents. Such long term consequences of corruption are no less real or damaging for being more removed from the individual act and need to be understood by officers whose job it is to ensure that laws aimed towards the security of people are not violated with impunity.

Connected with the above point is the more general impact that acts of favouritism may have on police, and public, perceptions of the law. When people such as politicians, police officers in general and friends of police officers are seen to be given favourable treatment with regards to the enforcement of violations of the law, this feeds into a culture of impunity. In the words of one analyst, such treatment increases people's perceptions of "the fallacy of impartial law enforcement."19 The law is seen to be malleable, not fairly applied to all and thus applicable only to those without influence or connections. These perceptions may have the reverse effect of Robert Klitgaard's "fry the big fish"20 approach to combatting corruption. Klitgaard recommends that to effectively send the message to the general public that corruption will not be tolerated, one needs to expose and prosecute prominent people in a society who are guilty of corruption, thereby making it clear that no one is above the law. The granting of immunity to some may have the opposite impact of undermining the legitimacy of the law, in effect contributing to a view of the law which sees it as applying "just for the little guys"21 and an attitude which views getting caught, not the actual infractions, as being the problem, or something to avoid.

This category refers to instances of public resources, in the form of police time, property or person power, being stolen, misdirected or unfairly allocated, thereby draining the resources available for proper or legitimate law enforcement ends. Often, the end result of this is that the overall efficiency and effectiveness of the criminal justice system is hampered. One example of this is when business owners, such as those operating a restaurant or pub, provide police officers with "perks" such as free or discounted meals or drinks and in return get more visits and protection from the police. In effect, they buy more service from the police, causing an improper distribution of police resources which results in other businesses or community members being treated unfairly and not receiving adequate police services. Furthermore, when this type of misallocation becomes even more serious, such as the case of some police commanders in Mexico selling "security services", in the form of on duty officers working as private security guards, to "merchants and bankers", it is no longer just a case of some favourable treatment towards a few businesses. Rather, it is clear that the policing resources, which are paid for with public money, are being diverted for entirely private ends.22

The selling of police resources can reach the point where legitimate police services are used for improper or even illegal ends. Examples of this are incidents uncovered by the Mollen Commission on corruption in New York of on duty officers using their uniforms or police vehicles to provide protection and escorts for drug transactions.23 This entails police powers being corruptly used for the pursuit and facilitation of criminal activity and while it goes beyond the diversion of resources, such diversion is one of its negative consequences.

Another example of this kind of diversion of resources is the case of Australian politicians in the 1970's using the police for "surveillance of troublesome politicians and other opponents of the ruling regime."24 However, in this case, when such subversion of police powers takes place within the context of a broader misuse of the police, it is unclear if individual officers were necessarily acting corruptly, as they may have simply viewed these tasks as part of their job, with no extra personal incentive or reward. Nevertheless, it is clear that such a (mis)use of the police still results in a form of misallocation or diversion of resources from legitimate to illegitimate ends.

Some other forms of misuse of resources should also be mentioned at this point. Forms of misconduct such as sleeping on the job or absenteeism also serve as a drain on police resources and are therefore similar in impact to cases of "diversion". While such actions may not, strictly speaking, be defined as corrupt (since neither really uses any form of occupational power), they do reduce the ability of the police to operate effectively and, as a result, also deprive the public of services that have been paid for.

One final set of practices in this group are more general forms of "office" corruption that involve the abuse of powers not exclusive to the police. One example, cited by James Morton in his survey of police corruption in Britain, is of senior officers using workers, such as gardeners, who are being paid with police funds, to do private work.25 In Victoria, Australia, as a response to large sums of cash being stolen by police from the pool of lost money turned in by members of the public, one police department simply "covered the losses through its general budgetary process allowing the thief to escape with the cash."26 Here, both the theft and the decision to not cover up for the perpetrator resulted in a misuse of public resources. Finally, outright theft from public resources, such as the alleged collusion between a police inspector and a community policing forum member in the Northern Province to embezzle money from a "peace rally fund"27 is a further example of the corrupt depletion of public resources.

This section discussed those "less direct"effects that most corrupt acts have in common. Such effects are not so much about any identifiable victims being harmed but rather have more to do with negative consequences for the organisational culture of the police and the relations between the police and the public. The costs discussed here are perhaps less immediately perceptible, but no less significant. They damage areas such as the morale of honest officers, the level of integrity of the police and the degree to which citizens are willing to co-operate with the police. Thus their impact needs to be seen in a broader context.

One of the most universal and damaging effects of corrupt acts, especially of those viewed as "petty" or without victims, is that any one act contributes to an attitude or culture which is conducive to future acts of corruption. Every instance of corruption bends or violates a rule or law and, similar to the granting of impunity, may contribute to an officer's perceptions of the law as applying differently to different people and increase the ease with which violations can be rationalised. Lawrence Sherman points to this in his study of how officers become corrupt. He espouses what may be called an "evolutionary view" of corruption, where there is a progress in "moral depravity" with a corrupt officer beginning with minor acts and possibly ending up committing major violations.28

The first opportunities for corruption that an officer is exposed to and may take advantage of are usually what are viewed as minor violations - such as petty theft from a store that has been broken into or a small bribe for not enforcing a parking violation. An officer may justify such corrupt acts as having no "real" victim and therefore harmless. However, it is here that an officer's self-image can begin to change, from an honest person committed to upholding the law to one that may sometimes break a rule or two her/himself. With each infraction, further violations become more palatable and gradually, more serious crimes may be able to be rationalised. For example, an officer who regularly commits "harmless" thefts from crime scenes or drug busts is more likely to "take the next step", such as soliciting corrupt funds for protecting illegal gambling rackets, than an officer who refuses the initial opportunities. A little over a year ago, there was a story in Business Day of an officer who was found guilty of "violating a corpse by removing its heart" so that he could sell it.29 Once an officer has undertaken such an overtly pre-planned activity, one that required more than just taking advantage of opportunities that came his way, one wonders to what degree he is still able to retain any moral constraints on his actions or still view himself as having sufficient integrity to be a police officer.

A similar point has been made by many analysts with regards to the progression of vice-related corruption as well as its connections with other corrupt acts with more direct victims. Sherman asserts that the process between taking a bribe for allowing a bar to remain open for an hour longer to accepting money for allowing drug deals is a gradual one filled in by steps such as "looking the other way" for prostitution and gambling offences in return for a pay-off.30 With each step, a more serious (from the officer's point of view) violation is overlooked and rationalised by being victimless and thus "ok" to not enforce. What may happen is that eventually an officer's frame of reference has changed so much that an activity once thought unimaginable (i.e., "helping drug pushers")31 may become acceptable. Even within the parameters of colluding with drug syndicates, there are degrees of wrongdoing, degrees that can eventually become blurred. As David Sisk has pointed out, officers who initially draw the line at accepting bribes for not enforcing laws dealing with the possession or selling of drugs may soon be induced to "promote the criminal organizations" that pay such bribes and "such promotion will include a reluctance to enforce laws against crimes with victims when committed by these same organisations."32

Besides changing an officer's self-image or perception of what is acceptable, petty corrupt acts can lead to more serious ones in other ways as well. One way is when the giving and taking of bribes becomes so routine or common that it is almost expected. A range of activities, such as kickbacks from towing operators and legal firms, bribes for speeding up firearm license applications or paying commanding officers in order to receive vacation time (as happens in Mexico city),33 can contribute to such an atmosphere flourishing. Even "gifts" from members of the community, where no exchange takes place (i.e., the officer provides no immediate service for the gift), can lead to an officer becoming accustomed to receiving "perks" or payments in the course of her/his job. As the National Director of the Anti-Corruption Unit Stefan Grobler points out, officers find it very easy to adjust to having a higher income, to the point where they may become dependent on corrupt funds to maintain their lifestyle.34

In addition to the effects that committing corrupt acts has on an officer her/himself, it also has an impact on the general culture of a police organisation. Each time an officer commits a corrupt act in front of other officers, the group's tolerance level for such behaviour may increase. By taking small kickbacks or bribes or engaging in petty theft, corrupt officers send out a message to each other that such behaviour is acceptable and perhaps even encouraged. These messages or signals help officers "size up" others in the organisation, differentiating between those who will commit corrupt acts and those who will not. Furthermore, they affirm the attitude that "the formal rules", either of society or of the police organisation, "are largely a sham". Instead of such rules, what is to be followed is the informal "code" of the sub-group of peers that often forms the most important reference group for an officer.35 Petty corrupt acts also play an important role in socialising new recruits into this sub-culture. An illuminating example is provided by one former officer who, on his first shift, witnessed his "old timer" partner steal "25- or 30-cent candy bars" from the supermarket. Upon entering the patrol car, the partner insisted he share in the "loot" and told him that "everybody did it and that [he] should get used to it."36 In such a case, where the value of the goods being stolen is so small, it is clear that the importance of the act is as much symbolic as it is material. Also, once an officer has committed a corrupt act, no matter how petty, her/his willingness or ability to expose or discuss the corrupt activities of others may be severely diminished.

The ability of the behaviour of corrupt officers to "convert" those officers seeking to remain honest should not be underestimated, particularly where such behaviour is part of the culture of a particular police department. First, it scarcely needs to be pointed out that seeing their peers commit even minor acts of corruption can have a devastating impact on the morale of those officers who are committed to upholding the law. Second, by not going along with such corrupt activities, honest cops risk alienating themselves from their peers, a dire consequence indeed in such a close-knit occupation, especially when one considers that there may be situations when an officer's life may depend solely on the support provided by her/his peers. This isolation from one's peers and the low morale of an honest officer may be further compounded by the fact that an honest cop, by refusing to "play by the rules", can be hindered in her/his career advancement. More than one observer of police culture has noted the kinds of demotions, transfers and menial tasks that are the lot of an honest officer, largely as a result of the fact that they make the "wrong" arrests (i.e., enforcing violations against those who pay bribes or are influential) or do not go along with other officers' thefts and graft.37 In addition to the damage this does to an effective officer's productivity, such ostracisation may also lead to an honest officer, after considerable resistance, becoming corrupt.38

It should be noted that, in respect of the above processes of how corrupt acts become acceptable, forms of police misconduct other than corruption can also play a significant role. The Mollen Commission found that in addition to encouraging junior officers to steal or take bribes, senior cops socialised new recruits into a culture of breaking the rules by encouraging them to engage in acts of brutality, "as a rite of initiation to prove the officer is a tough or 'good' cop",39 i.e, one that plays by the rule of the peer group. Also, infractions committed by officers in an effort to do their jobs (which can be described as the use of "illegitimate means for legitimate ends"), such as lying in a police report in order to establish grounds for searching a suspect, may also lead to police officers viewing the law as not applying to them. One former detective in New York, Robert Leuci, claimed that it was such "well-intentioned" infractions which were his introduction to rule-breaking, but that they soon became "a casual thing" and not long after, he had "graduate[d] to bigger crimes" for personal gain.40

One other type of corruption which has a strong impact on spreading a culture of corruption, or at least allowing corrupt activities to flourish, is when officers collude in the covering up of corrupt acts. This can take a number of forms, from acts of misconduct, such as not properly following through on investigations or "burying" troublesome files (i.e., those cases that suggest some police involvement in corrupt acts), to illegal acts such as perjury. The motivation for such actions may vary. It may be personal gain in the form of an officer helping out a friend. Or it may be a kind of organisational gain, in the form of a general recognition and acceptance among the police that cops are to be given special treatment - treatment bordering on immunity from law enforcement. Or, as perhaps is often the case, such interference may be the result of a desire to try to avoid damaging publicity, either for a specific unit or for the police service as a whole. In any case, such actions are corrupt. Officers cannot decide whether or not a certain investigation ought to be pursued based solely on its possible negative consequences for their friends or for the police in general. By using police powers such as access to documents, influence over other officers or credibility in a court of law in order to effectively undermine an investigation they are guilty of, at the very least, serious misconduct and often of committing criminal acts. As asserted by the Mollen Commission, it is very unlikely that corrupt officers in New York would have been able to operate effectively without the collusion of usually honest cops such as commanding officers and those in the internal affairs department involved in the "burying" of files and the obstruction or prolonging of investigations involving corrupt activities by other police officers.41

One impact that basically all corrupt activities have is that they decrease public trust in, as well as respect for, the police. Any corrupt act - from citizens witnessing minor kickbacks (eg. from tow truck operators) or "gifts" given by business owners, to reports in the press of bribe taking or collusion with criminal syndicates - reduces the confidence people have in the fairness, integrity and honesty of police officers. Recently, a police inspector in Mpumalanga was found guilty of a variety of "petty" corrupt offences such as demanding "brandy and bags of peanuts from job applicants and residents applying for firearm licenses". The magistrate who sentenced him stated that, rather than inspiring confidence among citizens in the police, the former inspector "ha[d] convinced people that it is simple to buy the police" and that "his actions destroyed his community's trust in the police and the law".42 The damage that corruption does by reducing public confidence in the honesty of the police has a few different consequences.

Perhaps the most severe harm that a decrease in public trust of the police has is that it causes a deterioration in relations between citizens and officers and, as a result, reduces the effectiveness of policing in a community. As Mpumalanga Police Commissioner Alfred Malete has stated, a large number of arrests are "made due to the community co-operating with [the police] or reporting crimes to [the police]".43 Without such public involvement, police efforts in fighting crime are severely hampered. A case in point is the San Jose police department, who, before Joseph McNamara became police chief, had very poor relations with the city, marked by distrust and animosity on both sides. As McNamara states, officers needed to "realize that unless people reported crimes, provided evidence, served as witnesses and - when on juries - believed police testimony, criminals would not be convicted." It was only after efforts were made to repair relations between the public and the police that "the police made more arrests than ever and crime decreased to the point that San Jose became one of the safest large cities" in the United States.44

Thus, given the importance of public assistance to the police in fighting crime, it is easy to see the detrimental effect of police corruption. Perceptions of corruption result in a lack of trust in the police service. A poll taken last year revealed that 67% of respondents believed that members of the SAPS accept bribes and over half said that they felt "that the police lack credibility" and view them as being "corrupt and having no integrity".45 If people lose faith in the integrity of police officers, the amount of cooperation the police receive from the public also decreases. This can reach the point "where many people don't even bother to report many criminal activities"46 to the police, having no confidence in either the abilities or commitment of officers to solve cases. Perhaps the following statement referring to the impact of corruption on police community relations in the US Virgin Islands puts it best: "Public distrust of officers often means that victims and potential witnesses don't come forward and criminals go free."47

Another impact of the lack of public trust in police officers that occurs as a result of perceptions of corruption is the decrease in credibility that police officers have as officers of the court. As the Mollen Commission states, the impact of this on the performance of the criminal justice system "can be devastating." Public trust "in even the most honest officer" may be eroded, leading "the public to disbelieve police testimony" with the result being that "the guilty [are] set free after trial."48 Last year this scenario played itself out in the city of Philadelphia, with over one hundred convictions "overturned in cases involving six police officers who pleaded guilty last fall to corruption charges." As a result, one district attorney asserts that many "current cases that should result in convictions [are] being dismissed because juries and defense lawyers [are] increasingly questioning the integrity of police officers."49 To cite one more example, in the US Virgin Islands, "charges of corruption on the force are so widespread that defense attorneys routinely try to discredit police officers testifying in court."50

In understanding the impact of corruption on officer-citizen relations, one also needs to consider the role it plays in influencing police perceptions of their relationship with the rest of society. Many students of police culture have noted an "us. vs them" mind set being common among police officers.51 The secrecy, stress and danger of police work leads to an insular and close-knit occupational culture that results in a strong distinction being made between members of the police and regular citizens. Such a distinction often entails some officers seeing "the public as a source of trouble", or even as "the 'enemy'",52 and thus isolating themselves and their peers from the rest of society. This division may be further entrenched by a perception on the part of some officers of public animosity towards the police. Thus, any time an officer feels hostility from members of the public, her/his allegiance and loyalty to the community of officers may be strengthened and her/his ties with the community outside of the police weakened.

Corruption can be both a result and a cause of this separation of the police from society. The isolation of the police can lead to a divergence of officers' values from those that the rest of society at least professes to uphold. It may also result in a lack of recognition of, or concern over, the harmful effects that corrupt acts have on society. Thus, it can make committing such acts easier to rationalise or justify. At the same time, every instance of corruption can further reinforce the distance between society and the police by increasing public hostility and distrust towards the the police. Also, every time an officer commits a corrupt act, s/he may be affirming yet again her/his status as an outsider who follows the informal rules of a corrupt peer group, .not the formal rules of society. Thus the relationship between an "us vs. them" mentality among the police and incidents of corruption can be a circular one. As long as officers play by the rules of their peer group and the public continues to negatively label them, any rapprochement between the two is unlikely. A final point, perhaps particularly relevant with regards to South Africa, is that the negative labelling by society may be even more damaging if the police feel it to be hypocritical. That is, if there exists a feeling that most members in society also view the formal rules as being a sham, and act accordingly, then the police may feel even greater embitterment for being singled out and judged by a double standard.

A better understanding of the many effects of police corruption gives us a clearer motivation for why it ought to be combatted. Does it also provide some indications as to how one may be able to address the problem? Before concluding, I would like to suggest a few ways in which it may. First, in term of the implications of this analysis for the efforts of bodies such as the ACU, a few suggestions may be put forward. In an interview, Director Grobler stated that the ACU's priorities are those corrupt acts which have the most detrimental impact on the criminal justice system.53 Judging by the actual operation of the ACU, these would seem to be generally those identified in the first section under "at whose expense", such as the sale of firearms, docket theft or collusion with car hijacking rings. It is suggested that other practices identified in this section, such as the falsification of evidence or testimony, receiving kickbacks from legal firms or the receipt of payments from private businesses should also be listed as priorities, if there is evidence of their occurence.

In addition, while it is certainly appropriate that the ACU focus on these forms of corruption which have the most serious and direct short term consequences, one also needs to consider a few questions: To what degree are the more serious corrupt acts the end result of a process of becoming corrupt? Is their existence facilitated by an acceptance or tolerance of more petty forms of corruption? Of course, one needs to recognise the devastating and direct impact that more serious forms of corruption have on individual victims and the functioning of the criminal justice system and thus make attempts at curbing such corruption. However, some unit or body, perhaps the ACU, also needs to take responsibility for addressing other forms of corruption which may have longer term effects. If as, Director Grobler has stated, the primary concern of anti-corruption work is to combact corrupt acts "which have an impact on the way officers do their jobs",54 then there certainly needs to be a recognition and prioritisation of the need to address the earlier acts which may lead to the more serious ones.

In addressing these earlier acts it will not only be necessary to make use of investigative measures. Longer term strategies - such as education and in-service training - are also needed. Arguably some of the resources which are spent on lengthy and expensive investigations might be better utilised in training, education, increasing accountability or closer supervision, especially during an officer's first couple of years on the service?

In particular the training of recruits should focus more on discussing the effects of, and likely opportunities for, engaging in corruption. Especially with regards to the spreading of a culture of corruption, through "petty" or apparently victimless corrupt acts or the receipt of seemingly innocuous gifts, recruits need to be alerted properly about the possible complexities and moral risks that they will face in their line of work. In the words of Director Grobler, new officers have to recognise the "red flashes" or be able to hear the "alarm bells" of corruption very early in their careers.55 One of the major purposes of this paper was to assist police officers in recognising the very serious consequences of corrupt actions. If police officers are able to recognise these consequences this recognition may serve as a preventive measure against corruption, particularly if officers internalise the view that corruption does indeed have victims and that even minor acts can have a very damaging impact on how they do their job.

Finally, as was noted by the Mollen Commission, honest police officers are among the most important resource in the fight against corruption. They may be witness to a variety of corrupt acts and experience first hand the very damaging consequences of corruption. Thus, they have both the opportunity and the motive to speak out against corruption. However, as we have seen, one of the effects of corruption is the way in which it ostracises and may silence honest officers, especially in situations where commanding officers are acting corruptly by "looking the other way" with regards to corrupt cops. Thus, a major task in fighting corruption needs to be to "provide constant support and recognition to officers who, by reporting corruption, choose to do what is right rather than what their [peer group's] culture expects of them." It must be made clear that "those who expose corruption will be rewarded, and those who help conceal it punished."56 Honest officers need to acknowledge the harm that even minor corrupt acts may cause and take steps to oppose each instance which they are witness to.

Freedom – Investigative Journalism Stories & Articles

Posted: at 1:52 pm

The Founder of Scientology, L.Ron Hubbard, was part of the generation whose crucibles were World War II and the advent of nuclear weapons that could vaporize civilization. The stakes were so high, victory was either a win or a lossthere were no draws or rematches. Another great man of that era, Englands Winston Churchill, commented that without victory, there is no survival.

Mr. Hubbard imbued Scientology with one paramount imperative: survival. But to survive, humanity had to flourish, had to be free. The one impulse in Man which cannot be erased is his impulse toward freedom, Mr.Hubbard wrote in 1954, his impulse toward sanity, toward higher levels of attainment in all of hisendeavors.

The Church of Scientology has traveled that path for more than six decades, growing and strengthening. At every step in its first several decades, the religion was assaulted by totalitarian and manipulative interestsin governments, organized psychiatry, pharmaceutical conglomerates, the small minds of the religiously intolerant. The Church won, won and won againand, by the way, won some more.

At the helm of Scientology for the last 30 years, David Miscavige has had a single, driving purpose: to spread the survival tools of Scientology to every corner of the globe and, thereby, halt the lurching downward spiral of civilization. The vast majority of the job is building the young religion, for today and for all tomorrows to come.

Thats called expansion. It takes hard work to establish a global Church. The spiritual path of Scientology becomes available to more people, who see that it works. That Church grows, carries out humanitarian programs that push back against the darkness of social decay, crime and mental and spiritual slavery. The Church opens groups and missions, which grow into Churches of their own, and the cycle accelerates.

Aiding all that is the dazzling momentum of the religions publishing, filmmaking, broadcasting and online dissemination endeavors. The greatest advance in that arena came in 2016, with the opening of a renowned and vintage Hollywood studio that is now Scientology Media Productions.

All of these episodes of growth are recounted in this special year-in-review issue of Freedom, the voice of the Church. The real beneficiaries of the progress and the triumphs in these pages are youevery man, woman and child on the planetbecause our goal is freedom and survival for all.

Pole Camera Surveillance Under the Fourth Amendment …

Posted: at 1:47 pm

Placing a video camera on a utility pole and conducting surveillance can be a useful law enforcement tool to gather information without requiring an in-person presence by officers at all times. But this tool may be subject to the Fourth Amendment restrictions. This post reviews the evolving case law, particularly since the United States Supreme Court ruling in United States v. Jones, 132 S. Ct. 945 (2012).

Jeff Welty in a 2013 post reviewed video surveillance generally, not just pole cameras, and discussed Jones and the few cases decided in light of its ruling. This post, after reviewing Jones, will discuss a few pole camera cases decided in federal courts since his post and whether officers should seek approval from a court before conducting pole camera surveillance.

United States v. Jones. Officers installed a GPS device without a valid search warrant on a suspected drug-traffickers vehicle and then tracked the vehicles movements for about four weeks. The holding of Jones was that the installation of the GPS tracking device on a suspects vehicle was a Fourth Amendment search because it involved a physical intrusion (a trespass) into the vehicle for the purpose of obtaining information. In addition, five Justices (the four who joined Justice Alitos concurrence in the judgment plus Justice Sotomayor, who also had joined the Courts opinion) expressed the view that prolonged GPS monitoring intrudes upon a suspects reasonable expectation of privacy and is a search under the Fourth Amendment. These Justices reasoned that although short-term monitoring of a suspects movement on the public roads may not intrude upon a reasonable expectation of privacy, long-term monitoring generates so much information about a suspects movements and activities that the aggregate effect is an invasion of privacy.

Although Jones involved tracking a suspects movements, it could be used to support a broader argument about long-term electronic surveillance. One could contend that under Jones, while officers are free to observe a suspects residence from the public streets or a neighbors property to see who comes and goes, permanent round-the-clock video surveillance is substantially more intrusive and constitutes a search under the Fourth Amendment.

Post-Jones cases on pole camera surveillance. The Jones ruling revived the trespass theory in Fourth Amendment analysis concerning what constitutes a search, so the trespass theory and the separate reasonable expectation of privacy theory both must be considered in appropriate cases.

Trespass theory. All the cases that have considered the issue have rejected a defendants argument based on the trespass theory that the installation of the camera was a trespass under Jones, because in most cases the utility pole is not on the defendants property or, even it is located there, the utility had an easement to access the pole as needed. United States v. Nowka, 2012 WL 6610879 (N.D. Ala. 2012); United States v. Root, 2014 WL 4715874 (E.D. Wash. 2014); United States v. Wymer, 40 F. Supp.3d 933 (N.D. Ohio 2014).

Reasonable expectation of privacy theory. I have found one post-Jones cases that ruled that warrantless pole camera surveillance violated the Fourth Amendment under the reasonable expectation of privacy theory. That case is Shafer v. City of Boulder, 896 F. Supp. 915 (D. Nev. 2012), where a pole camera surveilled the defendants backyard without a search warrant for 24 hours a day for 56 days, and the camera was long-range, infrared, and waterproof. The defendants backyard was protected by a solid fence and within the homes curtilage. The court cited two pre-Jones cases in support of its ruling, but not Jones, probably because it was unnecessary to do so based on the facts.

Most of the cases have ruled that warrantless pole camera surveillance did not violate the Fourth Amendment under the reasonable expectation of privacy theory. For example, a recent federal appellate case, United States v. Houston, 813 F.3d 282 (6th Cir. 2016), found that ten weeks surveillance with a camera installed on a utility pole about 200 yards from a trailer used as a residence on a farm did not violate a residents reasonable expectation of privacy because the camera recorded the same view of the residence as that enjoyed by people on nearby public roads. The court believed that the Jones case did not require a different result. Interestingly, a concurring opinion in Houston believed that Jones required the officers to obtain a search warrant.

A few case have upheld surveillance with reservations, being bound by prior pre-Jones precedents. See, e.g., United States v. Garcia-Gonzalez, 2015 WL 5145537 (D. Mass. 2015).

There have been no North Carolina appellate court or United States Supreme Court cases on pole camera surveillance since Jones.

Advice to officers. Nothing in Jones or lower court cases after Jones calls into question the use of surveillance cameras that are focused on public streets, parks, and other public areas. For example, if drug activity is commonplace at a particular intersection, the Fourth Amendment does not preclude placing a surveillance camera on a light pole facing that intersection.

It would not be surprising if in the relatively near future the United States Supreme Court decides a case on pole camera surveillance, and there is a reasonable probability that the Court might rule that extensive video surveillance of a residence requires a search warrant or its functional equivalent, such as a court order. Of course, predicting future Court rulings is highly speculative and subject to reasonable disagreement.

In the meantime, a cautious officer may wish to seek a court order authorizing the use of a pole camera directed at a residence or at least consult with the officers agencys legal advisor or a prosecutor before deciding not to do so. No case or statute sets out the proper procedure for obtaining such an order, but it likely would be similar to obtaining a search warrant or other investigative court order that could be sought ex parte and would need to be supported by an affidavit establishing probable cause. If a court order is sought, the order might limit pole camera surveillance to a relatively short period, such as 30 days, and apply again if additional surveillance is needed.

Human height – Wikipedia

Posted: at 1:44 pm

Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect. It is measured using a stadiometer,[1] usually in centimetres when using the metric system,[2][3] or feet and inches when using the imperial system.[4][5]

When populations share genetic background and environmental factors, average height is frequently characteristic within the group. Exceptional height variation (around 20% deviation from average) within such a population is sometimes due to gigantism or dwarfism, which are medical conditions caused by specific genes or endocrine abnormalities.[6]

The development of human height can serve as an indicator of two key welfare components, namely nutritional quality and health.[7] In regions of poverty or warfare, environmental factors like chronic malnutrition during childhood or adolescence may result in delayed growth and/or marked reductions in adult stature even without the presence of any of these medical conditions.

The study of height is known as auxology.[8] Growth has long been recognized as a measure of the health of individuals, hence part of the reasoning for the use of growth charts. For individuals, as indicators of health problems, growth trends are tracked for significant deviations and growth is also monitored for significant deficiency from genetic expectations. Genetics is a major factor in determining the height of individuals, though it is far less influential in regard to differences among populations. Average height is relevant to the measurement of the health and wellness (standard of living and quality of life) of populations.[9]

Attributed as a significant reason for the trend of increasing height in parts of Europe are the egalitarian populations where proper medical care and adequate nutrition are relatively equally distributed.[10] Changes in diet (nutrition) and a general rise in quality of health care and standard of living are the cited factors in the Asian populations. Malnutrition including chronic undernutrition and acute malnutrition is known to have caused stunted growth in various populations.[11] This has been seen in North Korea, parts of Africa, certain historical Europe, and other populations.[12]Developing countries such as Guatemala have rates of stunting in children under 5 living as high as 82.2% in Totonicapn, and 49.8% nationwide.[13]

Height measurements are by nature subject to statistical sampling errors even for a single individual.[clarification needed] In a clinical situation, height measurements are seldom taken more often than once per office visit, which may mean sampling taking place a week to several months apart. The smooth 50th percentile male and female growth curves illustrated above are aggregate values from thousands of individuals sampled at ages from birth to age 20. In reality, a single individual's growth curve shows large upward and downward spikes, partly due to actual differences in growth velocity, and partly due to small measurement errors.

For example, a typical measurement error of plus or minus 0.5cm may completely nullify 0.5cm of actual growth resulting in either a "negative" 0.5cm growth (due to overestimation in the previous visit combined with underestimation in the latter), up to a 1.5cm growth (the first visit underestimating and the second visit overestimating) in the same elapsed time period between measurements. Note there is a discontinuity in the growth curves at age 2, which reflects the difference in recumbent length (with the child on his or her back), used in measuring infants and toddlers and standing height typically measured from age 2 onwards.

Height, like other phenotypic traits, is determined by a combination of genetics and environmental factors. A child's height based on parental heights is subject to regression toward the mean, therefore extremely tall or short parents will likely have correspondingly taller or shorter offspring, but their offspring will also likely be closer to average height than the parents themselves. Genetic potential and a number of hormones, minus illness, is a basic determinant for height. Other factors include the genetic response to external factors such as diet, exercise, environment, and life circumstances.

Humans grow fastest (other than in the womb) as infants and toddlers, rapidly declining from a maximum at birth to roughly age 2, tapering to a slowly declining rate, and then during the pubertal growth spurt, a rapid rise to a second maximum (at around 1112 years for female, and 1314 years for male), followed by a steady decline to zero. On average, female growth speed trails off to zero at about 15 or 16 years, whereas the male curve continues for approximately 3 more years, going to zero at about 1820. These are also critical periods where stressors such as malnutrition (or even severe child neglect) have the greatest effect.

Moreover, the health of a mother throughout her life, especially during her critical period and pregnancy, has a role. A healthier child and adult develops a body that is better able to provide optimal prenatal conditions.[12] The pregnant mother's health is important for herself but also for the fetus as gestation is itself a critical period for an embryo/fetus, though some problems affecting height during this period are resolved by catch-up growth assuming childhood conditions are good. Thus, there is a cumulative generation effect such that nutrition and health over generations influences the height of descendants to varying degrees.

The age of the mother also has some influence on her child's height. Studies in modern times have observed a gradual increase in height with maternal age, though these early studies suggest that trend is due to various socio-economic situations that select certain demographics as being more likely to have a first birth early in the mother's life.[14][15][16] These same studies show that children born to a young mother are more likely to have below-average educational and behavioural development, again suggesting an ultimate cause of resources and family status rather than a purely biological explanation.[15][16]

It has been observed that first-born males are shorter than later-born males.[17] However, more recently the reverse observation was made.[18] The study authors suggest that the cause may be socio-economic in nature.

The precise relationship between genetics and environment is complex and uncertain. Differences in human height is 60%80% heritable, according to several twin studies[19] and has been considered polygenic since the Mendelian-biometrician debate a hundred years ago. A genome-wide association (GWA) study of more than 180,000 individuals has identified hundreds of genetic variants in at least 180 loci associated with adult human height.[20] The number of individuals has since been expanded to 253,288 individuals and the number of genetic variants identified is 697 in 423 genetic loci.[21] In a separate study of body proportion using sitting-height ratio, it reports that these 697 variants can be partitioned into 3 specific classes, (1) variants that primarily determine leg length, (2) variants that primarily determine spine and head length, or (3) variants that affect overall body size. This gives insights into the biological mechanisms underlying how these 697 genetic variants affect overall height.[22]

The effect of environment on height is illustrated by studies performed by anthropologist Barry Bogin and coworkers of Guatemala Mayan children living in the United States. In the early 1970s, when Bogin first visited Guatemala, he observed that Mayan Indian men averaged only 157.5 centimetres (5ft 2in) in height and the women averaged 142.2 centimetres (4ft 8in). Bogin took another series of measurements after the Guatemalan Civil War, during which up to a million Guatemalans fled to the United States. He discovered that Maya refugees, who ranged from six to twelve years old, were significantly taller than their Guatemalan counterparts.[23] By 2000, the American Maya were 10.24cm (4.03in) taller than the Guatemalan Maya of the same age, largely due to better nutrition and health care.[24] Bogin also noted that American Maya children had relatively longer legs, averaging 7.02cm (2.76in) longer than the Guatemalan Maya (a significantly lower sitting height ratio).[24][25]

The Nilotic peoples of Sudan such as the Shilluk and Dinka have been described as some of the tallest in the world. Dinka Ruweng males investigated by Roberts in 195354 were on average 181.3 centimetres (5ft 1112in) tall, and Shilluk males averaged 182.6 centimetres (6ft 0in).[26] The Nilotic people are characterized as having long legs, narrow bodies and short trunks, an adaptation to hot weather.[27] However, male Dinka and Shilluk refugees measured in 1995 in Southwestern Ethiopia were on average only 1.764 m and 1.726 m tall, respectively. As the study points out, Nilotic people "may attain greater height if priviledged with favourable environmental conditions during early childhood and adolescence, allowing full expression of the genetic material."[28] Before fleeing, these refugees were subject to privation as a consequence of the succession of civil wars in their country from 1955 to the present. The tallest living married couple are ex-basketball players Yao Ming and Ye Li (both of China) who measure 228.6cm (7 ft 11 in) and 190.5cm (6 ft 3 in) respectively, giving a combined height of 419.1cm (13 ft 9 in). They married in Shanghai, China, on 6 August 2007.[29]

In Tibet, the khampas are known for their great height. Khampa males are on average 180cm tall (5ft 11 in).[30][31]

The people of the Dinaric Alps (mainly North Albanians and South Slavs) are on record as being the tallest in the world, with a male average height of 185.6cm (6ft 1.1 in) and female average height of 170.9cm (5ft 7.3 in).

Growth in stature, determined by its various factors, results from the lengthening of bones via cellular divisions chiefly regulated by somatotropin (human growth hormone (hGH)) secreted by the anterior pituitary gland. Somatotropin also stimulates the release of another growth inducing hormone Insulin-like growth factor 1 (IGF-1) mainly by the liver. Both hormones operate on most tissues of the body, have many other functions, and continue to be secreted throughout life; with peak levels coinciding with peak growth velocity, and gradually subsiding with age after adolescence. The bulk of secretion occurs in bursts (especially for adolescents) with the largest during sleep.

The majority of linear growth occurs as growth of cartilage at the epiphysis (ends) of the long bones which gradually ossify to form hard bone. The legs compose approximately half of adult human height, and leg length is a somewhat sexually dimorphic trait, with men having proportionately longer legs. Some of this growth occurs after the growth spurt of the long bones has ceased or slowed. The majority of growth during growth spurts is of the long bones. Additionally, the variation in height between populations and across time is largely due to changes in leg length. The remainder of height consists of the cranium. Height is sexually dimorphic and statistically it is more or less normally distributed, but with heavy tails.[citation needed] It has been shown that a log-normal distribution fits the data equally well, besides guaranteeing a non-negative lower confidence limit, which could otherwise attain a non-physical negative height value for arbitrarily large confidence levels.[32]

Most intra-population variance of height is genetic. Short stature and tall stature are usually not a health concern. If the degree of deviation from normal is significant, hereditary short stature is known as familial short stature and tall stature is known as familial tall stature. Confirmation that exceptional height is normal for a respective person can be ascertained from comparing stature of family members and analyzing growth trends for abrupt changes, among others. There are, however, various diseases and disorders that cause growth abnormalities.

Most notably, extreme height may be pathological, such as gigantism resulting from childhood hyperpituitarism, and dwarfism which has various causes. Rarely, no cause can be found for extreme height; very short persons may be termed as having idiopathic short stature. The United States Food and Drug Administration (FDA) in 2003 approved hGH treatment for those 2.25 standard deviations below the population mean (approximately the lowest 1.2% of the population). An even rarer occurrence, or at least less used term and recognized "problem", is idiopathic tall stature.

If not enough growth hormone is produced and/or secreted by the pituitary gland, then a patient with growth hormone deficiency can undergo treatment. This treatment involves the injection of pure growth hormone into thick tissue to promote growth.

Certain studies have shown that height is a factor in overall health while some suggest tallness is associated with better cardiovascular health and shortness with longevity.[33] Cancer risk has also been found to grow with height.[34]

Nonetheless, modern westernized interpretations of the relationship between height and health fail to account for the observed height variations worldwide.[35] Cavalli-Sforza and Cavalli-Sforza note that variations in height worldwide can be partly attributed to evolutionary pressures resulting from differing environments. These evolutionary pressures result in height related health implications. While tallness is an adaptive benefit in colder climates such as found in Europe, shortness helps dissipate body heat in warmer climatic regions.[35] Consequently, the relationships between health and height cannot be easily generalized since tallness and shortness can both provide health benefits in different environmental settings.

At the extreme end, being excessively tall can cause various medical problems, including cardiovascular problems, because of the increased load on the heart to supply the body with blood, and problems resulting from the increased time it takes the brain to communicate with the extremities. For example, Robert Wadlow, the tallest man known to verifiable history, developed trouble walking as his height increased throughout his life. In many of the pictures of the later portion of his life, Wadlow can be seen gripping something for support. Late in his life, although he died at age 22, he had to wear braces on his legs and walk with a cane; and he died after developing an infection in his legs because he was unable to feel the irritation and cutting caused by his leg braces.

Sources are in disagreement about the overall relationship between height and longevity. Samaras and Elrick, in the Western Journal of Medicine, demonstrate an inverse correlation between height and longevity in several mammals including humans.[33]

Women whose height is under 150cm (4ft 11in) may have a small pelvis, resulting in such complications during childbirth as shoulder dystocia.[36]

A study done in Sweden in 2005 has shown that there is a strong inverse correlation between height and suicide among Swedish men.[37]

A large body of human and animal evidence indicates that shorter, smaller bodies age slower, and have fewer chronic diseases and greater longevity. For example, a study found eight areas of support for the "smaller lives longer" thesis. These areas of evidence include studies involving longevity, life expectancy, centenarians, male vs. female longevity differences, mortality advantages of shorter people, survival findings, smaller body size due to calorie restriction, and within species body size differences. They all support the conclusion that smaller individuals live longer in healthy environments and with good nutrition. However, the difference in longevity is modest. Several human studies have found a loss of 0.5 year/centimeter of increased height (1.2 yr/inch). But these findings do not mean that all tall people die young. Many live to advanced ages and some become centenarians.[38]

There is a large body of research in psychology, economics, and human biology that has assessed the relationship between several seemingly innocuous physical features (e.g., body height) and occupational success.[39] The correlation between height and success was explored decades ago.[40][41] Shorter people are considered to have an advantage in certain sports (e.g., gymnastics, race car driving, etc.), whereas in many other sports taller people have a major advantage. In most occupational fields, body height is not relevant to how well people are able to perform, but nonetheless has been found to correlate with their success in several studies, although there may be other factors such as gender or socioeonomic status that explain this.[39][40][42][43]

A demonstration of the height-success association can be found in the realm of politics. In the United States presidential elections, the taller candidate won 22 out of 25 times in the 20th century.[44] Nevertheless, Ignatius Loyola, founder of the Jesuits, was 150cm (4ft 11in) and several prominent world leaders of the 20th century, such as Vladimir Lenin, Benito Mussolini, Nicolae Ceauescu and Joseph Stalin were of below average height. These examples, however, were all before modern forms of multi-media, i.e., television, which may further height discrimination in modern society. Further, growing evidence suggests that height may be a proxy for confidence, which is likewise strongly correlated with occupational success.[45]

In the eighteenth and nineteenth centuries, people of European descent in North America were far taller than those in Europe and were the tallest in the world.[10] The original indigenous population of Plains Native Americans was also among the tallest populations of the world at the time.[46]

In the late nineteenth century, the Netherlands was a land renowned for its short population, but today its population is among the world's tallest with young men averaging 183.8cm (6ft 0.4in) tall.[47]

According to a study by economist John Komlos and Francesco Cinnirella, in the first half of the 18th century, the average height of an English male was 165cm (5ft 5 in), and the average height of an Irish male was 168cm (5ft 6 in). The estimated mean height of English, German, and Scottish soldiers was 163.6cm 165.9cm (5ft 4.4 in 5ft 5.3 in) for the period as a whole, while that of Irish was 167.9cm (5ft 6.1 in). The average height of male slaves and convicts in North America was 171cm (5ft 7 in).[48]

American-born colonial soldiers of the late 1770s were on average more than 7.6cm (3 inches) taller than their English counterparts who served in Royal Marines at the same time.[49]

Average height of Americans and Europeans decreased during periods of rapid industrialization, possibly due to rapid population growth and increased economic inequality.[50] In early 19th century England, the difference between average height of English upper class youth (students of Sandhurst Military Academy) and English lower class youth (Marine Society boys) reached 22cm (8.7in), the highest that has been observed.[51]

Data derived from burials show that before 1850, the mean stature of males and females in Leiden, Netherlands was respectively 166.7cm (5ft 5.6 in) and 156.7cm (5ft 1.7 in). The average height of 19-year-old Dutch orphans in 1865 was 160cm (5ft 3 in).[52]

According to a study by J.W. Drukker and Vincent Tassenaar, the average height of Dutch decreased from 1830 to 1857, even while Dutch real GNP per capita was growing at an average rate of more than 0.5 percent per year. The worst decline were in urban areas that in 1847, the urban height penalty was 2.5cm (1in). Urban mortality was also much higher than rural regions. In 1829, the average urban and rural Dutchman was 164cm (5ft 4.6 in). By 1856, the average rural Dutchman was 162cm (5ft 3.8 in) and urban Dutchman was 158.5cm (5ft 2.4 in).[53]

A 2004 report citing a 2003 UNICEF study on the effects of malnutrition in North Korea, due to "successive famines," found young adult males to be significantly shorter.[specify] In contrast South Koreans "feasting on an increasingly Western-influenced diet," without famine, were growing taller. The height difference is minimal for Koreans over 40, who grew up at a time when economic conditions in the North were roughly comparable to those in the South, while height disparities are most acute for Koreans who grew up in the mid-1990s a demographic in which South Koreans are about 12cm (4.7in) taller than their North Korean counterparts as this was a period during which the North was affected by a harsh famine.[54] A study by South Korean anthropologists of North Korean children who had defected to China found that 18-year-old males were 5inches (13cm) shorter than South Koreans their age due to malnutrition.[55]

The tallest living man is Sultan Ksen of Turkey, at 251cm (8ft 3in). The tallest man in modern history was Robert Pershing Wadlow (19181940), from Illinois, in the United States, who was 272cm (8ft 11in) at the time of his death. The tallest woman in medical history was Zeng Jinlian of Hunan, China, who stood 248cm (8ft 112in) when she died at the age of 17. The shortest adult human on record was Chandra Bahadur Dangi of Nepal at 54.6cm (1ft 912in).

Adult height between populations often differs significantly. For example, the average height of women from the Czech Republic is greater than that of men from Malawi. This may be caused by genetic differences, childhood lifestyle differences (nutrition, sleep patterns, physical labor), or both.

Depending on sex, genetic and environmental factors, shrinkage of stature may begin in middle age in some individuals but tends to be universal in the extremely aged. This decrease in height is due to such factors as decreased height of inter-vertebral discs because of desiccation, atrophy of soft tissues and postural changes secondary to degenerative disease.

As with any statistical data, the accuracy of such data may be questionable for various reasons:

Air pollution – Simple English Wikipedia, the free …

Posted: at 1:44 pm

Air pollution is the pollution of air by smoke and harmful gases, mainly oxides of carbon, sulfur, and nitrogen.

Many of the world's large cities today have bad air quality.[1] Even 2,000 years ago, the Romans were complaining about the bad air in their cities. At that time, the air was thick with smoke from fires and the smell of sewers.[1] Air pollution has been a danger to human health and Earth's many ecosystems for a long time.

It has many pollutants (things that pollute the air) from natural sources. These pollutants include dust, sea salt, volcanic ashes and gases, smoke from forest fires, pollen, and many other materials.[1] In fact, there are many more natural pollutants than pollutants that humans make.[1] However, humans have adapted to most of these natural pollutants.[1]

Air pollution may be personal, occupational or community air pollution.

Air pollution is usually described as either primary pollutants or secondary pollutants. Primary pollutants are pollutants that are put directly into the air by humans or natural sources. Examples of primary pollutants are exhaust fumes (gas) from cars, soot from smoke, dust storms and ash from volcanic eruptions (as seen in the picture on the left).[1]

Secondary pollutants are pollutants that are made from chemical reactions when pollutants mix with other primary pollutants or natural substances like water vapor.[1] Many secondary pollutants are made when a primary pollutant reacts with sunlight. Ozone and smog are secondary pollutants. Ozone is a gas that stops harmful ultraviolet rays from the sun. When it is near the ground, though, it can poison people and other organisms.[1]

Human-made air pollution comes from many things. Most air pollution made by humans today is because of transportation. Cars, for instance, make about 60% of the human-made air pollution. The gases inside car exhaust, like nitrogen oxide, make smog and acid rain.

Human-made air pollution is also caused when humans set their farmlands or forest on wildfires producing soot ( a black powder composed mainly of carbon, produced when coal, grasses, wood etc. is burned ) from smoke, that can affect people and other living when exposed to the atmosphere.

Many industrial power plants burn fossil fuels to get their energy. However, burning fossil fuels can make a lot of oxides (chemical compounds that have oxygen and other elements inside). In fact, the burning of fossil fuels makes 96% of the sulfur oxides in the atmosphere. Some industries also make chemicals that make poisonous fumes (smoke).

Air pollution is not only on the outside. Homes, schools, and buildings can also have air pollution. Sometimes the air inside a building is even worse than the air outside.[1] Many things which humans use every day can pollute the air. Compounds inside carpets, paints, building materials and furniture also pollute the air, especially when they are new.

In buildings where the windows are tightly shut to stop air leaks, the air inside can be polluted more than the air outside.[1]

Acid precipitation is precipitation, like rain, sleet, or snow, that contains acids from air pollution. When fossil fuels are burned, they let out oxides into the air. When these oxides mix with water in the atmosphere, they make acid, which fall as precipitation.[1] Acid precipitation can kill living things like fish and trees, by making the place where they live too acidic. Acid rain can also damage buildings made of limestone and concrete.

A global concern is the greenhouse gases and the hole in the ozone layer in the stratosphere. The Earth's ozone layer protects life from the Sun's harmful ultraviolet rays, but in the 1970s, scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen. This lets more ultraviolet rays reach the Earth. During the 1980s, scientists found that the ozone layer above the South Pole had thinned by 50 to 98 percent.

On March 17, 1992, in Mexico City, all children under the age of 14 could not go to school because of air pollution. This does not often happen, but being exposed to air pollution every day can make people have many health problems. Children, elderly (old) people, and people with allergies especially, can have a lot of problems because of air pollution. Studies from the University of Birmingham showed that deaths because of pneumonia and air pollution from motor vehicles like cars are related.[2]

The World Health Organization said that 2.4 million people died because of the direct problems of air pollution.[3][4] Some of the problems include:[1]

In India in 2014, it was reported that air pollution had cut crop yields in the most affected areas by almost half in 2010 when compared to 1980 levels. There can also be increased yield of crops due to some air quality conditions.
