Physical violence against a student is wrong unless it is self defense. Circa 1954 first grade Pecos, Texas. Mrs. Pruitt would tie an out of control student into his chair for about and half hour or more. He was not hurt. He was humiliated and laughed at by the other students. It worked. Oddly the other students laughing at him had great effect.
Mrs. Pruitt was actually a very kind lady and good teacher.
My public school elementary principal paddled kids.
That was a real act of physical violence. That happened across the country.
All of that was illegal and these people should have been in prison for ten years, each time?
