McDonald v. City of Chicago

In McDonald v. City of Chicago (2010) 561 U.S. 742, the court held the Second Amendment right is applicable to the states through the due process clause of the Fourteenth Amendment, but "'repeat ed its assurances' that 'the right to keep and bear arms is not "a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose"'" and reiterated "that its holding 'did not cast doubt on such longstanding regulatory measures as "prohibitions on the possession of firearms by felons and the mentally ill . . . ."' (McDonald, supra, at p. 786.)
