The schools don't need the cane or whatever... they only need the full support of parents in disciplinary matters.
When I was at school, the cane was still in use. It wasn't the thought of the cane that acted as a deterrent - it was what would happen when my parents found out.
The most disruptive pupils are usually the ones whose parents march up to the school when their precious innocent little ones have been out of order, with the sole intention of undermining the teachers authority.
