The Federal Witness Protection Program (WITSEC) is a U.S. government initiative designed to protect witnesses who testify in criminal cases, particularly those involving organized crime or serious threats. Participants in the program receive new identities, housing, and financial support to ensure their safety and that of their families. WITSEC is managed by the U.S. Marshals Service and has been instrumental in securing the cooperation of key witnesses, which can lead to successful prosecutions. The program aims to reduce the risks faced by witnesses, allowing them to live without fear of retaliation from criminal organizations.
