I do know that there are some people who are severely abusive to themselves at times. In those circumstances a shock would quickly get them to stop. Restraint is another solution, just until they calm down. Also a mild sedative. The advantage of the shock is it can be administered very quickly. So I do see some of the other side.
The problem is the school doesn’t just use the skin shocks for dangerous and abusive behaviors. They also use it for very minor misbehavior, such as swearing wetting the bed and tensing up. There use of skin shocks for very minor behavior is well documented by news articles and JRC even admitted it on there own web site (they since to the page down but it is archived here: http://web.archive.org/web/20070831130017/http://www.judgerc.org/faqs.html see question 36 “Is it true that JRC uses skin shock to punish minor behaviors?” ). Also they do something called BRLs where they force the student to engage in a bad behavior and shock them weather they do it or not (see https://stopjrc.wordpress.com/2011/05/24/strait-from-the-horses-mouth/ which quotes JRC’s own website.) Also have you seen the video of a student shocked for not taking off his coat, tied to a board then shocked repeatedly (this was reported by Fox with actual footage): https://www.youtube.com/watch?v=ZtRGQRtwh2U
A friend of mine commented asking why they can’t talk the person down that is upset. This is a good point. Some say restraint should be a last resort.
