I was watching this show which featured a patient who would have frequent violent outburst, so I wondered: What happens to insane people who litterally cannot stop hitting things, be it walls, themselves, or people.(Even if they don't exist). I mean, there are restraining vests and special rooms, but you cant keep someone like that forever, right? What if a person could literally not stop fighting? Do psychiatric hospitals have laws and rules to prepare for such cases?
