Teenage violence

Apparently there was this 13 year old girl in Western Australia who physically assaulted her teacher. And all the guy could do was try to hide. If I was the teacher, I would have knocked her out. Seriously. If kids are gonna do that, that's an offence. You'd be perfectly justified in acting in self-defence. And if you say that it's not justified, well, pacifism is nice in theory and all, but when someone is punching you in the face, principles go out the window. Go on, hide. Do nothing. Pathetic.
