While a witness may only require protection until the conclusion of a trial, some witnesses are provided with a new identity and may live out the rest of their lives under government protection.
Witness protection is usually required in trials against organized crime, where law enforcement sees a risk for witnesses to be intimidated by colleagues of defendants. It is also used at war crime trials.
