From my (quite extensive) experience of Prison Officers, they are always very very careful in how they deal with incalcitrance. I've seen them 'in action' many times, and there are usually five, summoned by the alarm bell, who each handle one part of the prisoner (eg one takes a leg, other leg, one arm etc and always the head is protected) They have to watch their step as everything goes on a Report after the event, and any injuries have to be examined by the Prison Doctor. Believe me, abuse by officers is almost unknown, and I've spoken to many inmates about this. They call it 'bending you up' and it just means the head is pushed down so you can't bite an Officer. So IMHO, this chap was kicking off big time to have got his poor little toothy pegs busted. Usually, it's a fellow prisoner who gives one a clump in prison, not the officers. I know one should try to sympathise with this suspect, but I'm afraid I can't.
