When I saw this question I thought I hadn’t, but, come to think of it, yes, I have. It was done in the commission of a beating.
I was a sophomore eating in the lunch room at my high school, and could see outside to the park behind the school through the big floor-to-ceiling windows. I never ate outside, or I probably would’ve been assaulted. There were concrete areas of blocks and pathways in the park. 6 or 7 rough-looking boys came into the park one day right up to another little guy, and all of them except one proceeded to beat the crap out of him. They didn’t go to our school.
As the “kicker”, the largest boy, who was probably about 6’4”, shoved the little guy onto the ground on his face, then proceeded to pick him up from the back of his collar and waistline, hoist him above his head and drop him on the ground 2 or 3 times, right on the concrete. His wallet came out of his pocket, and a boy who I presume was the leader of this little gang opened it, took the money out and threw it at the kid.
While the whole thing was happening, nobody dared move. The security guys were a few moments too late to have stopped it, and got there as the boys were leaving. The entire incident only lasted a couple of minutes. It was that day I looked into transferring schools.
