I went to a very liberal private high school in the 80s. I remember it had a rifle range...which would be taboo today. Also we had an annual event called The Assassination Game, where most students carried toy dart guns around for weeks...this was a very, very liberal school. I just find it amazing how quickly things have changed.
I remember playing it in high school we played a version of the game where every one was given a name on a piece of paper that person was your target. the only way you could get the kill was if no one saw you do it. if there was a witness then that person would get your piece of paper with the name. the winner was the person who had the most slips of paper at the end of the week.. we played it serval times till the teachers found out about it and ended it at one point we had over one hundred players
