Identity theft: aggravated identity theft: a federal statute forbidding “aggravated identity theft” imposes a mandatory consecutive 2-year prison term on an individual convicted of certain predicate crimes if, during (or in relation to) the commission of those other crimes, the offender “knowingly . . . uses, without lawful authority, a means of identification of another person.” 18 U. S. C. §1028A(a)(1). Section §1028(a)(1) requires the Government to show that the defendant knew that the means of identification at issue belonged to another person (U.S.S.Ct., 04.05.09, Flores-Figueroa v. U.S., J. Breyer).
