No requirement to be in the 'militia' as some want to believe.

"District of Columbia v. Heller, 554 U.S. 570 (2008), is a landmark case in which the Supreme Court of the United States held in a 5–4 decision that the Second Amendment protects an individual's right to possess a firearm unconnected with service in a militia for traditionally lawful purposes, such as self-defense within the home and that Washington, D.C.'s handgun ban and requirement that lawfully-owned rifles and shotguns be kept "unloaded and disassembled or bound by a trigger lock" violated this guarantee."
