How we research this Report an error

In the United States the program is officially called the Witness Security Program, and the U.S. Marshals Service runs it. It was authorized by the Organized Crime Control Act of 1970 and amended by the Comprehensive Crime Control Act of 1984. The Marshals Service says it has protected, relocated and given new identities to more than 19,250 witnesses and family members since the program began in 1971.

Who gets in

The program is for government witnesses, and their immediate family, whose lives are in danger because of their testimony against drug traffickers, terrorists, organized crime members and other major criminals. Admission isn't automatic. Each potential witness is vetted by the law enforcement agency that sponsors them, the U.S. Attorney sponsoring them, the Marshals Service, and the Department of Justice's Office of Enforcement Operations, which makes the final call.

What it involves

Witnesses and families typically get new identities with documentation. They may also get funding for basic living expenses and medical care, plus job training and employment help. During pretrial conferences, trial testimony and other court appearances, the Marshals Service provides 24-hour protection.

The Marshals Service states that no participant who followed the program's guidelines has been harmed or killed while under its active protection.

Why it comes up in privacy conversations

Witness protection is the extreme version of something ordinary people also want: a life where the wrong person can't find your name and address. Most people never need a new identity, but anyone who has been threatened or stalked knows how much it matters that records don't lead to their front door.

  • Identity theft is someone using your identity without permission. In witness protection, a new identity is issued by the government to keep you safe.
  • Doxxing is publishing someone's private details to harass them. Witness protection exists to keep those details out of reach of people who want to harm a witness.

How to protect yourself

  1. 1

    Report threats to the police

    If you're being threatened because of something you know or did, contact local law enforcement. Witness protection is for government witnesses admitted through law enforcement and prosecutors, so you can't apply for it yourself.

  2. 2

    Keep your address out of public listings

    Search your name and address and see where they appear. Our doxxing entry explains how details end up public. Serus finds where your address and phone number are listed and removes them.

  3. 3

    Tighten your social media

    Remove your address, workplace and location from profiles and set them to private.
