ELI5: How does the witness protection program work exactly?
gpt
Certain people who testify to police or in court have a particularly high risk of attracting violent reprisals from people negatively affected by their testimony. For example, someone who provides law enforcement with information regarding members of a gang.

These people and their families are given new identities by the government and moved to a different part of the country. The idea is that with a new identity, it's much harder for people who wish to harm them to track them down.
