The Second Amendment (Amendment II) to the United States Constitution is the part of the United States Bill of Rights that protects the right of the people to keep and bear arms. It was adopted on December 15, 1791, along with the rest of the Bill of Rights. The Supreme Court of the United States first ruled in 2008 that the Second Amendment protects an individual right to possess and carry firearms.
In 2008 and 2010, the Supreme Court issued two landmark decisions officially establishing this interpretation. In District of Columbia v. Heller, 554 U.S. 570 (2008), the Court ruled that the Second Amendment protects an individual's right to possess a firearm, unconnected to service in a militia and to use that arm for traditionally lawful purposes, such as self-defense within the home within many longstanding prohibitions and restrictions on firearms possession listed by the Court as being consistent with the Second Amendment
