U.S. v. Vasquez

Record contained sufficient evidence to support defendant's conviction on charge of failing to register as sex offender after traveling in interstate commerce under Sex Offender Registration and Notification Act, 18 USC sec. 2250(a). Ct. rejected defendant's claim that govt. was required to present evidence that he had specific knowledge of his federal obligation to register as sex offender and found that: (1) govt. need only show that defendant had knowledge that he was required by some sort of law to register as sex offender; and (2) said showing was established when defendant stipulated that he was required under state law to register as sex offender. Ct. further rejected defendant's claim that Congress exceeded its authority under Commerce Clause when enacting sec. 2250(a).
