United States v. Hayes, ___ U.S. ___, 129 S.Ct. 1079 (Feb. 24, 2009) ("'[T]he touchstone of the rule of lenity is statutory ambiguity.' Bifulco v. United States, 447 U.S. 381, 387, 100 S.Ct. 2247, 65 L.Ed.2d 205 (1980) (internal quotation marks omitted). We apply the rule 'only when, after consulting traditional canons of statutory construction, we are left with an ambiguous statute.' United States v. Shabani, 513 U.S. 10, 17, 115 S.Ct. 382, 130 L.Ed.2d 225 (1994). Section 921(a)(33)(A)'s definition of 'misdemeanor crime of domestic violence,' we acknowledge, is not a model of the careful drafter's art. See Barnes, 295 F.3d, at 1356. But neither is it 'grievous[ly] ambigu[ous].' Huddleston v. United States, 415 U.S. 814, 831, 94 S.Ct. 1262, 39 L.Ed.2d 782 (1974). The text, context, purpose, and what little there is of drafting history all point in the same direction . . . .").
