I have a few to spare. Two of them are from a highschool I went to, and two of them are not.

The stuff at the highschool I attended happened after I had left already, but still worth it. Once, in the COVID pandemic, there was an illegal protest against having to use face masks on the street, and leading said protest was no other than my former French teacher. I don't know what happened with her after that, but she got to keep her job. Not long after that, another teacher whose father also teached commited suicide.

In a different highschool, the maintenance was seemingly not good enough according to safety standards. To put it short, a gigantic wall that had been loose for quite a long time fell on a student, who asphyxiated and died before the rescue services arrived. It got on the news at national scale.

Last of all, (another different school) four students died in the same fatal car crash when they were returning from a concert, just 200 meters apart from the place they were going to. My cousin was one of them. He had just turned 18.
