What it's about

The Court did not decide on the merits whether a defendant must admit every element of a charged crime before receiving an entrapment instruction.

Question presented

1. Whether the Ninth Circuit’s rule that a defendant is not entitled to an entrapment instruction unless he admits all elements of the offense, including the required intent, is consistent with this Court’s decision in Mathews v. United States, 485 U.S. 58 (1988). 2. Whether the Ninth Circuit’s rule that a defendant is not entitled to an entrapment instruction unless he admits all elements of the offense violates the Fifth and Sixth Amendments.
