"The Fifth Amendment provides, among other things, that no person shall be held to answer for a capital or otherwise infamous crime unless on presentment or indictment of a grand jury. This court has held that, in prosecutions by a state, presentment or indictment by a grand jury may give way to informations at the instance of a public officer." -- US Supreme Court, Palko v. State of Connecticut, 302 U.S. 319 (1937)"The Second Amendment declares that it shall not be infringed, but this, as has been seen, means no more than that it shall not be infringed by Congress." -- US Supreme Court, U.S. v. Cruikshank, 92 U.S. 542 (1875), Presser v. State of Illinois, 116 U.S. 252 (1886)
"To suppose arms in the hands of citizens, to be used at individual discretion, except in private self-defense, or by partial orders of towns, countries or districts of a state, is to demolish every constitution, and lay the laws prostrate, so that liberty can be enjoyed by no man; it is a dissolution of the government. The fundamental law of the militia is, that it be created, directed and commanded by the laws, and ever for the support of the laws." -- John Adams
