I used to go to a special ed school where they had 5 "steps" to deal with the bad behaviour, which you would advance or decline in depending on whether or not you behaved badly.
The first two steps were just warnings.
The third step was to sit you at a desk in the corner of the class room.
The fourth was to put you in a walled corner of the room. The walls of that corner didn't quite reach the cieling, and the way in was just a break in them.
The fifth step, was to put you in a small 5 by 5 foot room in the hallway. Kids inside that room frequenly attacked its door furiously whilst shouting curses. Often their shoes were taken from them, so that they couldn't attack it without hurting themselves, and so wouldn't attack it so much. I was only in it a few times, but I remember its door being littered wih dent marks.
Sometime people would try to run away from the school. That was funny.
They'd shouting things like "I'm free, FREE, so long mother f*****s!" when they ran.
P.S. Charging a Kindergardener for assualting a police officer is stupid.
