in their normal and ordinary as distinguished from technical meaning. United States v. Sprague, 282 U.S. 716, 731 (1931); see also Gibbons v. Ogden, 9 Wheat. 1, 188 (1824). Normal meaning may, of course, include an idiomatic meaning, but it excludes secret or technical meanings ... ." With that finding as an anchor, the Court ruled a total ban on operative handguns in the home is unconstitutional, as the ban runs afoul of both the self-defense purpose of the Second Amendment – a purpose not previously articulated by the Court – and the "in common use at the time" prong of the Miller decision: Since handguns are in common use, their ownership is protected.

The Court, additionally, hinted that other remedy might be available in the form of eliminating the license requirement for carrying in the home, but that no such relief had been requested: "Respondent conceded at oral argument that he does not 'have a problem with ... licensing' and that the District's law is permissible so long as it is 'not enforced in an arbitrary and capricious manner.' Tr. of Oral Arg. 74–75. We, therefore, assume that petitioners' issuance of a license will satisfy respondent's prayer for relief and do not address the licensing requirement."
