It is the height of irresponsibility to have a "no self defense" policy. It makes the pycho kid and his victim equal to be punished.
The pychos are still going to be pychos. THe good kids will know that they have to "take their beatings" and live in fear, or be punished for defending themselves.
It also teaches other children to be meek, submissive serfs too, too stand by while bullying goes on, because the retarded lefty teachers and administrators will just punish everyone equally.
And really, let's be real. There is a really good chance the pycho kid(s) have some angle that leads to them getting SOFTER treatment, either a handicap diagnosis, or being black or some such libtard shit.
