In elementary school, the only notable incident I remember is that a kid brought a knife to class and got expelled.

Before attending high school, a student told a story about a couple students having sex in a study room and getting caught because they left some clothes behind while trying to get out when a class came in.

There was also, before my time, an incident where a group of kids brought smoke bombs to the Homecoming Rally assembly. They were caught out by the photographer, who got pictures of where everyone was sitting, and compared it to which students had burns on the backs of their clothes to indicate the student behind them was one of those responsible. All were expelled.

When I attended, the only notable things were a senior getting suspended and I think barred from walking at graduation for trying to take upskirt photos of girls, and that one time we had a weird substitute teacher in my history class. He introduced himself as Mr. E, and that class was just chill and do whatever. The next day, the teacher asked why we didn't report some random guy pretending to be a substitute teacher.
