Far better the warm hand of a loving parent applied liberaly in youth than the cold logic of a judge and jury in adolescence. The worst form of child abuse in society is a lack of discipline at home and at school. We are generating a society scared to defend itself from abusive children, and scared to speak up and help teachers who try to deal with them at school. Assault is assault and you have a right to defend yourself from it, restrain them and if you hurt them in the process I think its their fault not yours.
