Liparota (D) was a co-owner with his brother in a sandwich shop in Chicago. D was indicted for acquiring food stamps in violation of §2024 (b)(1). The Department of Agriculture did not authorize petitioner's restaurant to accept food stamps. Evidence at trial showed that D purchased food stamps from an undercover agent for substantially less than their face value on three different occasions in the back room of his restaurant. The court rejected a trial instruction relating to the specific intent because it deemed the case to be a knowledge case rather than a specific intent case. D was convicted. D appealed based on his contention that the crime required a showing of specific intent.
