I would actualley first suggest she contacts the Department of education to get some advice from them. If it is the schools policy to suspend for that type of behaviour then he should be suspended- i am suprised that he hasn't already been suspended for hitting a teacher. She really needs to talk to the principal about the fact that she doesn't think it is fair the boy has been only given a detention and not been suspended, and like I said contact the department, and just get some more advice from them.
