Second Amendment to the United States Constitution – Wikipedia …

The Second Amendment (Amendment II) to the United States Constitution protects the right of individual Americans to keep and bear arms regardless of service in a militia. The right is not unlimited and does not prohibit all regulation of firearms and similar devices.[1]State and local governments are limited to the same extent as the federal government from infringing this right. The Second Amendment was adopted on December 15, 1791, as part of the first ten amendments comprising the Bill of Rights.

The Second Amendment was based partially on the right to keep and bear arms in English common-law and was influenced by the English Bill of Rights of 1689. Sir William Blackstone described this right as an auxiliary right, supporting the natural rights of self-defense, resistance to oppression, and the civic duty to act in concert in defense of the state.[2]

In United States v. Cruikshank (1876), the Supreme Court of the United States ruled that, "The right to bear arms is not granted by the Constitution; neither is it in any manner dependent upon that instrument for its existence" and limited the applicability of the Second Amendment to the federal government.[3] In United States v. Miller (1939), the Supreme Court ruled that the federal government and the states could limit any weapon types not having a reasonable relationship to the preservation or efficiency of a well regulated militia.[4][5]

In the twenty-first century, the amendment has been subjected to renewed academic inquiry and judicial interest.[5] In District of Columbia v. Heller (2008), the Supreme Court handed down a landmark decision, expressly holding that the amendment protects an individual right to possess and carry firearms.[6][7] In McDonald v. Chicago (2010), the Court clarified its earlier decisions limiting the amendment's impact to a restriction on the federal government, expressly holding that the Fourteenth Amendment applies the Second Amendment to state and local governments to the same extent that the Second Amendment applies to the federal government.[8] Despite these decisions, the debate between the gun control and gun rights movements and related organizations continues.[9]

There are several versions of the text of the Second Amendment, each with capitalization or punctuation differences. Differences exist between the drafted and ratified copies, the signed copies on display, and various published transcriptions.[10][11][12][13][14][15][16][17] The importance (or lack thereof) of these differences has been the source of debate regarding the meaning and interpretation of the amendment, particularly regarding the importance of the prefatory clause.

One version was passed by the Congress,[18][19][20][21][22]

As passed by the Congress and preserved in the National Archives:[23]

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

As ratified by the States and authenticated by Thomas Jefferson, then-Secretary of State:[24]

A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
