Witness protection is a program designed to safeguard individuals who provide testimony in legal cases, particularly those involving serious crimes. Participants, often referred to as witnesses, may face threats or retaliation from those they testify against. The program offers new identities, relocation, and support to ensure their safety. The U.S. Marshals Service administers the federal witness protection program, which has been in operation since 1970. It aims to encourage cooperation with law enforcement by providing a secure environment for witnesses and their families, allowing them to live without fear of harm while contributing to the justice system.
