violence begets violence.I experienced 1st hand - on my own hands! - corporal punishment aged about 12.
Did me no harm. I didn't even tell my Dad until I was 16 and out of school for fear of what would also come my way.
Yet amazingly, I have grown up and fully developed into a decent rounded human being.
Anyway, my reason for quoting you is to ask what would you instill as a punishment to these unruly kids at school? Don't say detention either. Been there, done that. CP came later as the result of an on the way to school violence episode, of which I was a victim, but I still got whacked by the Head of Year. You're involved, you get whacked!
