Under this Court's decision in Morrissey v. Brewer, 408 U.S. 471, 489 (1972), a defendant "is guaranteed the right to confront and cross-examine adverse witnesses at a revocation hearing, unless the government shows good cause for not producing the witness." Does the government meet the good cause standard if it subpoenas a witness, but informs the witness that it will not enforce the subpoena?
