I do agree, and having witnessed a few people who were utterly flying on drink & drugs I'm all for restraint so long as it's humane and appropriate, people really just LOSE IT - not just their temper, all ability to think like a reasoning human. I've probably mentioned this before but I've seen it take 5 or 6 BIG male coppers to hold down one smallish woman, who was in a state - and brain injury is no different, anything that makes the person lose their grip means they don't need or actually benefit from the same treatment you'd give someone who was in possession of all their marbles. JMO.
