All jurisdictions rely on a witness protection program like this when they have one, but only as a last resort. So it's the tail end, the extreme of the continuum, of protection practices. That's not the one we should rely on all the time. This is one of the reasons I welcome the recent developments about cooperation with provincial programs, where sometimes all that is required is assistance in changing identity.
