Is Elliott entitled to present his entrapment byestoppel defense under the "silver platter" doctrine?

1 Elliott also argues that he was entitled to present his entrapment-by-estoppel defense under the "silver platter" doctrine which prohibits federal authorities from using evidence seized unconstitutionally by local authorities. See Elkins v. United States, 364 U.S. 206, 233 (1960). But his reliance on the "silver platter" doctrine is misplaced. The doctrine requires a district court to exclude evidence obtained unconstitutionally, not to admit otherwise inadmissible evidence of entrapment by estoppel.
