How true. All of my male teachers back in the early '60s were WWII combat vets and our principal fought at Iwo Jima so they took no crap from the students. I saw a number of "tough guy" students slammed against the wall by teachers.
I still remember when I was in the eighth grade seeing one of the nuns slamming a sixth-grader against the school wall just outside the main entrance. She was saying things to him as she was doing it (that I couldn't hear), and the kid had a look of sheer terror on his face. I still remember the kid's name. I had a sister who was in this kid's class, and she said he deserved everything he got from the nun.
