Was the mom there with the student? If so, that’s a really crappy place for her to be in. The person who’s supposed to protect her and be on her side is letting some middle age man hit her. So not cool.
I was in third grade at a school assembly when the principal came up to me and the kid next to me, told us to come with him. He took us to his office and accused us of whistling during the assembly. We hadn’t done that. He used a paddle on us a couple times. IIRC, it was more of a psychological thing since there were no marks or anything, but it sure left an impression about getting accused, tried and convicted for something I didn’t do. I was ashamed, didn’t tell my parents (neither did the school). Years later, I mentioned it to my dad. He was surprised and angry that they did that. He said he wished I had told him because he would have gone down there and… done something. (Pop was not an aggressive man, but he probably would have at least made the principal apologize.)
I hope so. As a parent, I couldn’t fathom this. I feel for the student.
