Those who are suspected of involvement in a criminal act by Federal prosecutors will sometimes be offered a Proffer, which is a type of limited immunity from prosecution in exchange for cooperation. Sometimes the Proffer is initiated by the prosecutors, and other times a person and their attorney will request a Proffer. Handling a Proffer situation properly is of the highest importance, as it can greatly affect whether a person is prosecuted and the outcome of such a case.
