sentences:  District of Columbia v. Heller
  
  District of Columbia v. Heller, 554 U.S. 570 (2008), was a landmark decision of the US Supreme Court ruling that the Second Amendment protects an individual's right to keep and bear arms, unconnected with service in a militia, for traditionally lawful purposes, such as self-defense within the home, and that the District of Columbia'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.It also stated that the right to bear arms is not unlimited and that guns and gun ownership would continue to be regulated.
