In prosecution on federal-funds bribery charge, Dist. Ct. did not err in granting govt.’s motion in limine to preclude defendant from raising entrapment defense. Record lacked evidence of inducement on part of govt. where tapes and transcripts indicated that defendant had initially raised possibility of changing zoning designation for proposed club in exchange for $5,000 payment and ultimately indicated that he needed initial $5,000 payment plus supplemental payment of one or two thousand dollars to pay others to effectuate zoning change. Record also showed that defendant was active and willing participant in his discussions with undercover agent.
