I'm no fan of caning or physical punishment for crimes, but isn't that how a lot of bullying ends? The victim snaps, the bully gets beaten up or injured in some way and the latter finds an easier target to go after?
At the end of the day, a bully picks on those they perceive to not be a threat, whether that's a school bully using physical violence or a copyright/patent troll harassing individual creators and small companies. Being forced to go against someone with more resources or who can inflict serious damage against the aggressor is how a lot of bullies get shut down.
I would suspect that the vast majority of bullying ends when the victim is able to escape from the bully -- by changing schools, etc.
We hear about victims snapping and beating up their bullies because that makes a good story. How about victims who snap but then are beaten up (because the bullies are often bigger and more used to violence) even more? Probably much more common.

The unspoken rule is that the victim must only do hand-combat. They cannot use weapon in any way. If the victim uses weapon to defend themselves, they will be in the wrong.
Life is hard for victims. They are often bullied because they are weaker. And the only way out is to do hand-combat.
