Improper Vouching The defendant’s argument that the prosecutor engaged in improper trial tactics is also without merit. The Government argues that since the defendant did not object to any of the alleged misconduct at trial, we review for plain error. See United States v. Kerr, 981 F.2d 1050, 1053 (9th Cir.1992).
