You or I would never have been able to continue disrupting and threatening other students at a public school after just 2 or 3 incidents like this. This perp is what prisons were made for.
Prisons gotta eat too.
I would bet every class of a certain size has their share of brawlers and tough guys always getting into fights. In my class there were about four or five who were constantly getting into fights or starting trouble. But they always did their fighting outside of school. There were no brawls, riots, or students assaulting teachers.
Interestingly enough, three or four ended up in prison and one narrowly avoided prison.
Back when I was in high school (stone age to my kids), we had a Dean of Boys and a Dean of Girls. Both had big paddles that they used frequently on backsides. One trip to the Dean’s office was usually sufficient.
Too bad we have made such progress in our schools.
