Hard men who use violence in the pursuit of crime are surprisingly ill-prepared for life inside. In society they resort to getting physical to get their own way and this is the one thing that the law comes down very harshly on, to the extent that it is not tolerated. Knowing a prisoners crime the prison officers need to address the miscreants abhorrent behaviour early-doors. Stripping the bastard naked and making him feel humiliated is a good start.
