>that was repeated until all involved parties stoped misbehaving.

The canning would vastly shorten the time span on which all parties stop misbehaving while the bullying continues. I was bullied as a kid and the school didn't do anything. When my father tried to reason with the bully's family he discovered they were just awful, violent people, bullies, all of them. When he came home, frustrated, he sat me and said something like "uhm, well, ok, listen, I went to talk to the boy's parents and... well... the next time he bothers you just beat the shit out of him. I'll deal with the school" and the quoted the motto of my country: "by reason or by force". Some things just works faster than diplomacy and all shit get sorted out without extending the suffering for most parties involved.
