The Use of Cooperating Witnesses in Federal Prosecutions

Pace Law’s Distinguished Fellow in Criminal Justice Mimi Rocah recently appeared on the “Law & Crime” network to discuss the government’s use of a cooperating witness with host Caroline Polisi. Ms. Rocah explained the process of using a cooperating witness in a federal prosecution. Although a cooperator must first plead guilty to the highest possible crime (and possibly other unrelated crimes), the incentive to cooperate in a federal investigation is significant. If the government finds that the cooperator has information against more culpable parties and they testify truthfully, the government will ask the judge to sentence the cooperator below the mandatory minimum under the sentencing guidelines. See the interview here.
