I can't imagine what the police go through. I was brought up to not get in trouble. Sometimes I did, but if I saw someone stronger than myself, if they challenged me, I would have tried to stay out of trouble. I have a good friend that teaches autistic children in public school. They are often uncontrollable. Understandably many parents like it when they leave their troubled children with others. Meantime, these children can hit, threaten others but the teachers must not retaliate. I wouldn't take a job like that.
