To be clear, I am not about to justify any sort of violence anywhere. That said...
Many violent and disruptive students were just kids with special needs. And I don't mean mental conditions or anything like that.
I mean a kid that would do WAY better if he was in a trade class doing something that motivates them, rather than being frustrated and forced to endure a rubbish secondary education, several hours crammed into a small room with other people and getting nowhere.
But of course that's more difficult to implement than a generic standardising/equalising pipeline of norm-conforming average citizen production.
I think we should focus on students already trying to be a positive influence in the school, rather than catering to the bottom quintile. After all, that is how schools got in this situation in the first place.
