Whole Class Punisment15

It never happened at my school, so far as I know, but a friend of mine who went to a school where there was a lot more CP said he’d been caned as part of a group punishment. I think someone had drawn an obscene picture on the blackboard, and the teacher decided that if the culprit wouldn’t come forward, he would cane the whole class. Everyone got two on the hand: the teacher set the class some work, and then walked from desk to desk, whacking each boy in turn. The teacher told each boy to hold out his non writing hand. My friend claimed to be able to write just as well with either hand, and the teacher said it was up to him which one he held out, but suggested it should be the left. This has always seemed horribly cold-blooded to me. Not only was this man going to inflict pain on my friend for something he almost certainly hadn’t done, but he was having a calm, polite conversation about it before hand.
