SiFive hones Risc-V cores for more processing power and fewer watts – Electronics Weekly

The release has been dubbed 20G1, as the company has switched from year-month naming to year-release naming: 20G1 being the first general release of 2020 and encapsulates nine months of hard work and progress at SiFive as we move to a new release schedule driven by our road-maps and aligned to customer engineering cycles, it said.

Enhancements to the high-end Linux-capable U7-Series application processor are claimed to have reduced power consumption by more than 25%, while increasing load bandwidth up to 2.8x for streaming data applications such as AI acceleration that is comparing the 20G1 U74 processor with the previous (August 2019) U74 running running Dhrystone. Other SiFive cores also feature reduced power consumption, SiFive is highlighting the power saving in the U74 as a best case, the company told Electronics Weekly.

Another change is that the low-end E3-Series and E7-Series are now available with the RISC-V embedded extension, called RV32E, which can reduce 28nm chip area by up to 11% compared to RV32I implementation.

Based on customer feedback, RV32E will be a popular option for product designers who need area-constrained high-performance embedded CPUs, said SiFive, adding: The SiFive 3-, 5-, and 7-Series cores have been refreshed with new, enhanced real-time capabilities, bringing deterministic performance for high-reliability designs to SiFives product portfolio.

An add-on to 20G1 is support for SiFive Shield Hardware Cryptographic Accelerator intellectual property, offeringa configurable mix of AES, SHA, and TRNG functions to add secure root-of-trust and hardware cryptography acceleration.

In addition, pre-integration of SiFives Insight trace and debug block will speed use of Arms CoreSight tool, said SiFive: By seamlessly integrating with CoreSight, developers can integrate SiFive Risc-V based cores into mixed ISA [instruction set] designs and maintain their existing development environment. Insight is the industrys first pre-integrated debug and trace IP for RISC-V processor cores.

One last announcement is aimed at users of FreeRTOS:SiFives Freedom E SDK now includes FreeRTOS v.10, with source code and build scripts. Alongside the FreeRTOS kernel, the SiFive Freedom E SDK features several FreeRTOS-based examples, including using physical memory protection to enable secure run-time operations, said the company. Associated board support packages have been upgraded to include SVD (System View Description) for debug environment integration.

Poll: 62% of Americans Say They Have Political Views They’re Afraid to Share – Cato Institute

Nearly athird (32%) of employed Americans say they personally are worried about missing out on career opportunities or losing their job if their political opinions became known. These results are particularly notable given that most personal campaign contributions to political candidates are public knowledge and can easily be found online.

And its not just one side of the political spectrum: 31% of liberals, 30% of moderates and 34% of conservatives are worried their political views could get them fired or harm their career trajectory. This suggests that its not necessarily just one particular set of views that has moved outside of acceptable public discourse. Instead these results are more consistent with a walking on eggshells thesis that people increasingly fear awide range of political views could offend others or could negatively impact themselves.

These concerns are also crosspartisan, although more Republicans are worried: 28% of Democrats, 31% of independents, and 38% of Republicans are worried about how their political opinions could impact their career trajectories.

Americans with diverse backgrounds share this concern that their employment could be adversely affected if their political views were discovered: 38% of Hispanic Americans, 22% of African Americans, 31% of White Americans, 35% of men, 27% of women, 36% of households earning less than $20,000 ayear, and 33% of households earning more than $100,000 ayear agree.

Some are more worried about losing their jobs or missing out on job opportunities because of political views. Those with the highest levels of education are most concerned. Almost half (44%) of Americans with postgraduate degrees say they are worried their careers could be harmed if others discovered their political opinions, compared to 34% of college graduates, 28% of those with some college experience, and 25% of high school graduates

Interview: Rep. Jody Hice on Defund the Police and Big Tech Censorship – Merion West

(Getty)

But there is no question that weve got some major issues, and free speech is so dependent these days on these big tech companies, so they have to be very careful that free speech is protected. And, of course, theres a pattern now that shows otherwise

On July 21st, Merion West editor Erich Prince was joined by Rep. Jody Hice, a Republican who represents Georgias 10th congressional district in the U.S. House of Representatives. (Rep. Hice has also joined Merion Westfor previous discussions in 2018 and 2019.) In this conversation, Mr. Prince and Rep. Hice discuss recent unrest in the country, including the Defund the Police movement, which has gained particular inroads recently in cities such as New York and Minneapolis. Rep. Hice then also weighs in on recent concerns about free speech, including allegations that various technology companies have an anti-conservative bias.

Good morning, Congressman. Nice to talk to you again and thanks so much for your time. I want to start off by quickly saying that I understand the President was in Atlanta last weekand that you had the chance to fly with him on Air Force One. How was that experience?

Great experienceits always wonderful to be with the president, but to be on Air Force One is just icing on the cake to be with him in that environmentjust an amazing experience all the way around.

I saw a video you posted on Twitter showing your constituents the conference room [on board], and you shared with them a message about getting involved in politics.

Yeah, you know we are a country of We the People; our voice matters. I feel like Im an example of that myself; [I] never dreamed Id be in a place like this. And I just want to encourage other people that their voices matter; their votes matter; and to step up to the plate in whatever capacity they can and to be involved. I thought the place, the conference room on Air Force One, was appropriate for getting that message out on.

Jumping ahead, I read your June op-ed in The Daily Caller End RacismNot the Police, as well as your recent letters co-signed with a few other colleagues to the mayors of New York, Los Angeles, and Minneapolis. Obviously, this anti-police moment is gaining a lot of traction. What do you think is the best way to turn the tide against this from your perspective?

I think, in fact, Americans in generalin every polltheyre opposed to defunding the police or eradicating police departments. People understand that its impossible to have law and order if you dont have law enforcement in the mix. And this attempt to remove all law enforcement in their capacity to maintain law and order is only going to create further chaos and more crime. And, of course, thats what were seeing in all of those three cities that you mentioned: Crime is up; violent crime is up. Its ludicrous to think that we can maintain a civil society without police departments and law enforcement.

And closer to home for youobviously, Atlantas not your districtbut that was an area that was hit pretty hard by things. And there were reports about morale suffering within law enforcement, such as reports of walkouts by police in Atlantas Zone 6 in particular.What are you hearing around the state of Georgiawhether in your district or around the statefrom law enforcement?

As you mention, Atlanta is not in my district, but I have spoken to many law enforcement individuals in the 10th district of Georgia, and its a difficult time. We are not seeing the same type of protests as have happened in Atlanta and some other major cities. What protests there have been in our district have been peaceful and that type of thing, but the overarching question that you bring up is: How is the Defund the Police movement impacting these various departments, sheriff departments, police departments?

And it is impacting them. They are having great difficulty in hiring people, even receiving applications from individuals who are interested in law enforcement. And thats been an area in the past that people have been proud to be in law enforcement, to be public servants in that capacity, but now its a different scenario. And even in rural parts of our nation, that is having an impact.

On the flip side, one does see some of this effort to show extra support for police. I saw a weekend or two ago in Queens [New York] that there was a very sizable pro-police march, so perhaps some of the people on the other side [of this debate] are also trying to make their voices heard.

Yes, and I think youre going to see more of that because, again, the vast majority of Americans understand that the vast majority of police officers are great people, and theyre public servants. Are there bad actors? Of course, there are, and those are the individuals we need to go after. Thats where the problems that exist need to be dealt with and eradicated. But to punish entire departments is doing nothing other than punishing entire communities and cities. Its just the wrong way to go about it, and I think the majority of Americans are keenly aware of that, and they will be supporting the police departments.

So, yesterday when I was getting together this interview discussion, I was planning to ask you about free speech in a number of places, and one of the places was big tech. Then I saw your letter that you tweeted this morning about free speech, Twitter, big tech, and potential censorship. I know the Tom Cotton Twitter controversy a couple of weeks ago received a lot of attention. So, in the aftermath of recent events and free speech being arguably very much in the crosshairs, what is your thinking about the path forward as far as big tech?

Actually, there is going to be a hearing in judiciary with the big four big tech companies next week, so we will have a better feel next week as to where this whole thing is going to go. But there is no question that weve got some major issues, and free speech is so dependent these days on these big tech companies, so they have to be very careful that free speech is protected. And, of course, theres a pattern now that shows otherwise, and we want to stop that before it becomes a serious infringement upon peoples right to speak.

And I know a lot of people were concerned in particular with this perception that Twitter was employing its new fact-check feature disproportionately against conservatives, for example.

Yes, theres multiple examples of that, and, of course, there have been hearings trying to deal with those issues in the past during which [these companies] have assured us that their algorithms do not show bias towards conservative groupsbut its not just about algorithms. Its about the individuals who are working there, meaning those employees who do, in fact, carry biases, and they are able to override the algorithms. So, its a little disingenuous for these companies to say that our algorithms do not show any bias because thats not the only problem thats involved in this. And I think that issue has now come to light, and now well have to approach it from not only the systems themselves but also the people who are working those systems.

Lastly, college campuses have been a major discussion point when it comes to free speech. What are you seeing in Georgia [on this front]? Are you thinking about if this becomes an issue at various Georgia universities how to ensure free speech is taken care of there?

Right now, the big issue is if were even going to have college campuses and people meeting on those campuses, obviously. But, in the past, there have definitely been some issues in Georgia and across the country. And we are going to continue to keep a close pulse on that everywhere in this country, including college campuses. They should be the place where people have the right to express their ideas in the public square without fear of intimidation, or harassment, or punishment.

Unfortunately, that has not always been the case on college campuses, and there have been multiple lawsuits, and most of those lawsuits come out favorably. And, yet, the problem continues, so we will continue fighting and keeping a pulse on it here from the federal level as best as we can. Many of us up here at least have that as a major, important issue, and we will continue protecting the free rights of these students.

I appreciate your time, Congressman. Always nice to touch basethank you.

Always nice to talk with you. Thank you, Erich.

New Poll: 62% Say the Political Climate Prevents Them from Sharing Political Views – Cato Institute

50% of strong liberals support firing Trump donors, 36% of strong conservatives support firing Biden donors; 32% are worried about missing out on job opportunities because of their political opinions

A new Cato Institute/YouGov national survey of 2,000 Americans finds that 62%of Americans say the political climate these days prevents them from saying things they believe because others might find them offensive. This is up from 2017 when 58% agreed with this statement. Majoritiesof Democrats (52%), independents (59%) and Republicans (77%) all agree they have political opinions they are afraid to share.

Strong liberals stand out, however, as the only political group who feel they can express themselves:58%of staunch liberals feel they can say what they believe.

Centrist liberals feel differently, with52%who feel they have to selfcensor, as do 64% of moderates, and 77% of conservatives. This demonstrates that political expression is an issue that divides the Democratic coalition between centrist Democrats and their left flank.

Read the full survey report and results here.

Whats changed? In 2017 most centrist liberals felt confident (54%) they could express their views. However today, slightly less than half (48%) feel the same. The share who feel they cannot be open increased 7points from 45% in 2017 to 52% today. In fact, there have been shifts across the board, where more people among all political groups feel they are walking on eggshells.

Although strong liberals are the only group who feel they can say what they believe, the share who feel pressured to selfcensor rose 12 points from 30% in 2017 to 42% in 2020. The share of moderates who selfcensor increased 7points from 57% to 64%, and the share of conservatives rose 70% to 77%, also a7point increase. Strong conservatives are the only group with little change. They are about as likely now (77%) to say they hold back their views as in 2017 (76%).

Selfcensorship is widespread across demographic groups as well. Nearly twothirds of Latino Americans (65%) and White Americans (64%) and nearly half of African Americans (49%) have political views they are afraid to share. Majorities of men (65%) and women (59%), people with incomes over $100,000 (60%) and people with incomes less than $20,000 (58%), people under 35 (55%) and over 65 (66%), religious (71%) and nonreligious (56%) all agree that the political climate prevents them from expressing their true beliefs.

50% of Staunch Liberals Support the Firing of Trump Donors

Nearly athird (31%) of Americans say theyd support firing abusiness executive who personally donated to Donald Trumps reelection campaign for president. This share rises to 50% among strong liberals who support firing business executives who personally donate to Trump.

36% of Staunch Conservatives Support Firing Biden Donors

The survey finds that cancel culture goes both ways. Nearly aquarter (22%) of Americans support firing abusiness executive who personally donates to Democratic presidential candidate Joe Bidens campaign. This share rises to 36% among strong conservatives who support firing Biden donors. These results are particularly notable given that most personal campaign contributions to political candidates are public knowledge and can easily be found online.

32% Worry Their Political Views Could Harm Their Employment

Nearly athird (32%) of employed Americans say they are worried about missing out on career opportunities or losing their job if their political opinions became known. Americans across the political spectrum share these concerns: 31% of liberals, 30% of moderates, and 34% of conservatives are worried their political views could get them fired or harm their career trajectory. This suggests that its not necessarily just one particular set of views that has moved outside of acceptable public discourse. Instead these results are more consistent with a walking on eggshells thesis that people increasingly fear awide range of political views could offend others or negatively impact themselves.

These concerns cut across demographics and partisan lines: 28% of Democrats, 31% of independents, 38% of Republicans, 38% of Hispanic Americans, 22% of African Americans, 31% of White Americans, 35% of men, 27% of women, 36% of households earning less than $20,000 ayear, and 33% of households earning more than $100,000 ayear fear their political opinions could impact their career trajectories.

The Daily Standard World News – The Daily Standard

Screen capture from a mobile phone in Hong Kong Friday, July 17, 2020, At first glance, this graphic design poster may look like it's made up of mere circles - however, from afar, viewers can make out the eight Chinese characters for "Liberate Hong Kong, Revolution of our times." A protester who held this poster at a protest on July 6 was detained briefly by police but was later released. (AP Photo/Vincent Yu)

HONG KONG (AP) - It was one of the first protests in Hong Kong after a feared national security law came into effect.

Among a dozen or so lunchtime demonstrators at a luxury mall in the Central business district, a man raised a poster that - when viewed from afar - read in Chinese, "Liberate Hong Kong, revolution of our times."

The government had just banned the slogan, saying it had separatist connotations and so ran afoul of the new security law's prohibition of secessionist acts.

Shortly after, riot police entered the mall, shooing away onlookers. They detained the man, telling him the slogan was banned. But when officers looked at the poster up close, no words could be made out. It merely had circular shapes against a contrasting background. They snapped a few photographs of the poster and let him go.

Since the imposition of the security law -- which bans secessionist, subversive and terrorist activities, as well as collusion with foreign forces, with penalties of up to life imprisonment -- anti-government protesters in Hong Kong, and those supporting the movement, have adapted their methods to try to make their voices heard without violating the legislation.

Before the law took effect June 30, protesters often held up colorful posters plastered with slogans that ranged from condemning the Chinese government to calling for Hong Kong's independence. Since then, they have become creative in obscuring their messages.

Many of the protesters at the luxury mall held up blank pieces of white paper to protest against China's "white terror" of political repression. Other posters are designed to circumvent bans on slogans. The government has not yet made clear if such forms of expression are illegal.

The law has had a chilling effect on "yellow shops" that support the protest movement. Many have removed protest artwork and sticky notes bearing words of encouragement from customers, out of fear that they could land them in trouble with the authorities.

A Hong Kong Cafe, known as a "yellow shop" because its owners expressed sympathy for protesters, has a wall decorated with blank post-it notes in Hong Kong Thursday, July 9, 2020. Stores that supported the protest movement by putting up protest artwork and sticky notes filled with words of encouragement from customers have since taken them down, out of fear that its contents could land them in trouble with the authorities. Instead, they have put up blank sticky notes as a way to show solidarity with the movement. (AP Photo/Vincent Yu)

Some shop owners, like Tan Wong, have instead put up blank sticky notes to show solidarity with the movement.

"We are doing this right now because (the shop) is private property. We are trying to tell Hong Kong people that this is the only thing that we 'yellow shops' can do," said Wong, who runs Kok Kok Chicken, a Korean fried chicken store.

"If we do not persist, we would no longer be able to deliver our message to others," he said.

Yu Yee Cafe, a Hong Kong-style diner that serves fast food, has covered its windows with blank sticky notes and even displays an origami figure of Winnie the Pooh, a playful taunt of Chinese President Xi Jinping. Chinese censors briefly banned social media searches for Winnie the Pooh in China after Xi's appearance was compared to the cartoon bear.

"I wonder if there's still rule of law if sticking a (blank) piece of paper on the wall is illegal," said Eddie Tsui, one of the diner's customers. "It's just using a different way to express our demands. If you don't allow us to protest that way, we'll find another way."

The use of blank paper or sticky notes to protest is a changing form of resistance, according to Ma Ngok, an associate professor of politics at the Chinese University of Hong Kong.

"They put up blank notes so that even if the government wants to prosecute them, there is nothing that can be used against them," he said.

Instead, they have put up blank sticky notes as a way to show solidarity with the movement. (AP Photo/Vincent Yu)

Protesters in Hong Kong have also come up with alternative slogans to circumvent the ban on "Liberate Hong Kong, revolution of our times."

Some users quote the initials of the romanization of the eight Chinese characters in the banned slogan -- "GFHG, SDGM." Others have changed the words entirely to terms that sound similar but mean very different things. One alternative slogan now reads "Patronize Hong Kong, Times Square," a reference to a popular shopping mall in the city.

A popular protest anthem, "Glory to Hong Kong," has had some of its lyrics changed, with protesters replacing the words with numbers in Cantonese that sound approximately like the lyrics.

The circumventing of bans on slogans is reminiscent of how mainland Chinese internet users come up with creative ways and similar-sounding words to talk about sensitive issues without triggering censorship under the "Great Firewall of China," where censors delete posts containing sensitive terms and make such keywords unsearchable on online platforms.

"There is a long history of censorship where we know that people will find ways to circumvent the system, no matter how you regulate," said Fu King-wa, associate professor at the University of Hong Kong's journalism school.

"Sometimes, censorship can backfire, triggering more people to discuss an issue because they think that if it is censored, then it must be something important," he said.

Heres one way to make daily covid-19 testing feasible on a mass scale – MIT Technology Review

Its impossible to contain covid-19 without knowing whos infected: until a safe and effective vaccine is widely available, stopping transmission is the name of the game. While testing capacity has increased, its nowhere near whats needed to screen patients without symptoms, who account for nearly half of the viruss transmission.

Our research points to a compelling opportunity for data science to effectively multiply todays testing capacity: if we combine machine learning with test pooling, large populations can be tested weekly or even daily, for as low as $3 to $5 per person per day.

In other words, for the price per test of a cup of coffee, governments can safely reopen the economy and halt ongoing covid-19 transmissionall without building new labs and without new drugs or vaccines.

Most people get tested for the coronavirus because they experienced symptoms, or came in close contact with someone who did. But as offices and schools come under pressure to reopen, organizations will need to grapple with an unpleasant truth: relying on symptoms to guide testing will miss asymptomatic and pre-symptomatic cases, and put everyone at risk.

The current alternatives, though, are not appealing. Infrequent testing (monthly seems to be the default in many proposals) or haphazard screening allow active cases to spread the virus for weeks before its caught. And the price is still high at $100 to $200 or more per test.

Pooled testing, guided by machine-learning algorithms, can fundamentally change this calculus. In pooled testing, many peoples samples are combined into one. If no virus is detected in the combined sample, that means no one in the pool is infected. The entire pool can be cleared with just one test.

But theres a catch: if anyone in the pool is infected, the test will be positive and more testing will be required to figure out who has the virus.

So a key part of knowing how to pool is knowing the likelihood that certain people in the group will be positive, and separating them from the rest. How do we know that risk? Thats where machine learning comes in.

The risk of infection is evolving rapidly in the United Statesthe relative odds in New York and Florida have reversed in a matter of weeks. Risk also differs significantly between peoplecompare a health-care worker with an employee working remotely. Estimating this risk for each person is a perfect job for machine learning.

Using publicly available data from employers and schools, epidemiological data on local infection and testing rates, and more sophisticated data on travel patterns, social contacts, or sewage (pdf), if available, modelers can predict anyone's risk of having covid-19 on a day-by-day basis. This allows highly flexible approaches to pooling that drive huge efficiency gains.

Another advantage: pooled testing gets more efficient when disease prevalence is lower. If a populationsay, all students at a universityis tested daily, the risk of infection is dramatically lowered for everyone in the group, simply because testers remove positives from tomorrows pool when they diagnose them today. That means tomorrows pool can be even larger, which reduces the number of tests needed and thus the cost of testing the population. And with more frequent testing, people who are infected but dont have symptoms can stay home, further reducing spread and making pooled testing even more efficient.

As a result, high-frequency pooled testing with machine learning costs far less than you might think. According to our analysis, testing daily costs only twice as much as testing monthly. And daily testing can actively suppress the virus, whereas monthly testing really only allows us to see how badly things have gone.

This effect can be so powerful, in fact, that under some conditionssuch as in meatpacking plants or nursing homesincreasing frequency can actually lower the number of tests needed, and thus the cost of testing a population, in a given time period. You read that right: testing more often can actually be less expensive for the health-care system.

The last pillar of prevention through testing requires accounting for the viruss spread between people and, therefore, for risk that is correlated. Using machine learning to model social networks has been a growing focus for researchers in computer science, economics, and other fields. Such algorithms, combined with data on jobs, classrooms, university dorms, and many other settings, allow machine-learning tools to estimate the potential that different people will interact. Knowing this likelihood can make group testing even more powerful.

Is high-frequency pooled testing feasible in the real world? While we dont want to minimize the logistical challenges, they are just thatchallenges, not deal-breakers. The US Food and Drug Administration has just approved the first use of pooled testing, and research increasingly shows that this technique is sensitive enough to detect positive cases. So as long as labs are willing, testers can start pooling today.

Though some have called into question the feasibility of pooling given the scale of the current outbreak, this is only a challenge because we traditionally rely on coarseand, as we show in our paper, potentially inaccurateestimates of virus prevalence in large populations. Instead, machine learning can give us the precise individual-level estimates we need to make pooling work even at high prevalences, by identifying those likely to test positive and keeping them out of large pools.

Frequency also pays huge dividends when virus prevalence is high. Before pooled testing is implementedsay, at a factory or schoolthe entire population could complete a one-time screening. Infected people would stay home until they recovered, and high-frequency pooled testing would keep prevalence low by catching disease early.

The logistics of sample collection and pooling in different settings must also be addressed. Were encouraged by the increasing evidence for products, some approved by the FDA, that allow people to collect and submit their own test samples. One is based on saliva, which means collection costs can be kept low even at large scale.

Its high time for high-frequency testing to become a core part of the US strategy to combat covid-19 and reopen the economy. Pooled testing that harnesses the power of machine learning makes paying the associated costs not only viable but, when weighed against the alternative of prolonged closures, a tremendous deal.

Library of Congress Wants To Try Adding Humans to Automated Processes – Nextgov

The Library of Congress, the biggest physical repository of information in the world, has been digitizing its resources, expanding its digital library and developing automation tools to manage its collection. As those tools bear fruit, Library officials now want to reintroduce humans to the process.

The Librarys Digital Innovation Labs Section has undertaken a range of programs aimed at maximizing the use of digital collections and supporting emerging research methods, including using machine learning and crowdsourcing prototypes, according to a solicitation posted Tuesday to beta.SAM.gov. Now, the Library of Congress seeks to build on these initial experiments to further examine models that expand access to digital collections by combining digitally-enabled human participation with computational methods, otherwise known as human-in-the-loop approaches.

As the Librarys digital collection expands, it needs help properly tagging and verifying the metadata attached to the content. Machine learning tools have been plugging along at this task through the pilot programs, but Library officials want humans to help verify the work is being done correctly, as well as ethically.

Through the contract, the Library wants to procure at least two experimental prototypes using human-in-the-loop workflows to model, test, and evaluate different ethical approaches to applying crowdsourcing and machine learning methods to Library digital collections that enhance collection usability, utility, discoverability and user engagement.

Per the solicitation, at least one of the two prototypes will focus on improving metadata through crowdsourcing methods. As users add feedback on the accuracy of the derived metadata, those results will in turn be funneled back into the automation tools to serve as training data for a machine learning algorithm that shall be applied to Library digital collections to create enhanced metadata.

Library officials stressed the need to incorporate user-centered design in the process or risk alienating the volunteers and researchers contributing to the project. The solicitation pushes this concept beyond basic interface design and requires the contractors to consider user motivations and needs in the workflow.

Workflows shall be adaptive to different use cases and user profiles, to ultimately facilitate meaningful and productive user interactions with the Librarys digital collections, according to the statement of work.

Bids are due by noon August 5. The contract will run from September 1 through June 30, 2021.

Emails Show Dept. of Justice Suggested OANN Should Call the FBI About Software Used by NPR to Accept News Tips – Law & Crime

A series of recently-released emails show that officials with the U.S. Department of Justice (DOJ) once suggested that the Federal Bureau of Investigation (FBI) might care to talk about NPRs use of encryption to accept news tips to public radio reporters.

Perhaps even more surprisingly, the suggestion to ask law enforcement about public radios newsgathering practices was made to one of NPRs rivals in the media industry: the far-right One America News Network (OANN).

Emails obtained by Freedom of Information Act (FOIA) journalist Jason Leopold show the order of events.

Can you find out if DOJ is cool with NPR running a Tor-enabled tip email? OANN reporter Neil McCabe asked DOJs Office of Public Affairs (OPA) Director Lauren Ehrsam Gorey in April 2018.

Ehrsam did not personally field the question, per the email released under FOIA, but added OPAs then-principal deputy director Ian Prior because he handles national security questions.

You should reach out to FBI for this, Prior wrote.

According to the Electronic Frontier Foundation, a nonprofit group that supports internet privacy rights and civil liberties, Tor is a network and a software package that helps you anonymously use the Internet. Specifically Tor hides the source and destination of your Internet traffic, this prevents anyone from knowing both who you are and what you are looking at (though they may know one or the other). Tor also hides the destination of your traffic, which can circumvent some forms of censorship.

The software-network combination has, for years, been widely used by journalists and news organizations to keep digital information and identities secureparticularly when dealing with sources who have apprehensions about sharing their information. Whistleblower and dissident Edward Snowden famously used Tor to send information to various media outlets in 2013.

The privacy tool is generally not in disfavor with the U.S. government. In fact, Tors development was largely funded and developed by U.S. government agencies and research grants.

Whats more bizarre about the emails is that OANNs McCabe attempted to link the rules which he says govern military public affairs officers to NPRs news-gathering efforts.

McCabe offered the following information on background:

In Army public affairs, the reason public affairs soldiers do not break stories about crimes or corruption is that the Army actually has its own police force and detectives, the MPs [sic]. That makes it absurd that some reporter at an Army newspaper would be running down crimesrather, as soon as a public affairs soldier becomes aware of wrongdoing, he is supposed to report it to the authorities.

How is it then, that federal government employees could be running their own private silo for information about crimes or national security risks? his email continues.

The OANN reporter was apparently operating under the misapprehension that NPR employees are federal government employees. Though NPR was created by an act of Congress and is subsidized in small part by the government, the vast majority of its funding comes from membership fees. The organization itself is structured as a 501(c)(3) nonprofit corporation under the tax code, and its employees, therefore, do not work for the government and certainly not for the military.

Is DOJ synched [sic] up with NPR for reports of crimes or national security risks? McCabe asked. Does NPR enjoy any of the journalistic privileges that would protect sources or methods?

This is hack journalism of the highest order, Leopold, of Buzzfeed News, said on Twitter.

That characterization got McCabes attention.

Wait, he tweeted back. What is the problem with this inquiry? How did I become a hack over this? Not every inquiry is a gold mine, I was being pro-active and curious. Can I have my card back?

A smallish vanguard of information-armed individuals quickly chimed in by criticizing McCabe for his suggestion that NPRs employees are somehow likable to agents of federal law enforcement.

To which McCabe responded:

No. It doesnt.

Law&Crime reached out to NPR for a reaction. No response was forthcoming at the time of publication. If a response is received, it will be included here.
