I'm going to deal with punishment in schools. We had the strap, I got it only once, because of what I believe to be a fault in the administration of corporal punishment.
I'm left handed and we were compelled to use fountain pens. Mine used to unscrew due to the right hand threads on the bodies and the left hand twist of writing. A geography teacher wanted me to rewrite an essay as the first attempt was so badly blotted. I did this, with less blobs, but it was as good as it was going to be, so I wouldn't write any more. I was kept in after school, to no effect.
I was then sent to Big Jim Ridsdale. Over 6' tall, ex Guardsman, rugby player, careerist teacher specialising in sports, not intellect. I was walloped 6 times across the back of my little legs by a roaring, insensitive, moron.
If corporal punishment is to be used, it should not be at the discretion of a potentially extremist single individual; perhaps a 3 magistrate panel selected at random from among the staff? I don't know. Power in one man's hands with no access to reason or justice is wrong though.
For the record, I wanted to find out what happened to Big Jim. I found out. He used us a stepping stone to become headmaster of one of the city's notable grammar school until his retirement. As he grew older, he developed Parkinson's and died of it. I have no hesitation in saying it pleases me that at the end, he knew what it felt like to be helpless in the face of unstoppable evil.
