Good faith is recognized as a defense to a charge of mail or wire fraud. See, e.g., United States v. Casperson, 773 F.2d 216, 223 (8th Cir. 1985). For a discussion of the defense of good faith and the entitlement of jury instructions on this issue, see Green v. United States, 474 U.S. 925 (1985); see also Laura A. Eilers & Harvey B. Silikovitz, Mail and Wire Fraud, 31 Am. Crim. L. Rev. 703, 719 (1994) (and cases cited).
