When I was in the US during high school, my school had excellent discipline.
Corporal punishment was an option at my school, but extremely mild and extremely rare. I doubt that a kid who is contemplating entering a fist fight is going to be deterred by a possible paddling anyway.
The important point was that teachers had authority to write detention slips for disruptive students. Get 10 of those and you were yanked out of the regular clbuttroom schedule, and into "corrective learning".
If the disruptive types can be removed and dealt with early, you don't get an escalation in the first place. The right idea is not to worry about how to discipline a rapist (though I suppose it's important to have a procedure for everything), it's to maintain a level of order that prevents this from happening in the frst place.
But you seem to confuse "discipline" with "corporal punishment".
But again, you make the buttumption that absence of corporal punishment is "kinder" or softer. Doing it your way, you'd just let the clbuttroom get out of control, then beat the crap out of the kid who throws the first punch.
Doesn't work. You need to discipline the first kid who shows disruptive behaviour of any kind.
The kids would have bruises inflicted by teachers, as well as by the other kids.
