But I saw fights that were much worse, fights that ended in bleeding, cracked ribs and concussions, thankfully there was hospital across the road. This was in a rural region high school, in the 90s, I can only imagine what its like in places with actual gangs, today, etc.

The worse part about it is, you tell the teachers, they do nothing substantial, then you're a snitch. If you do the one thing likely to solve the problem, which is fight back, you're punished, and now the cops are called and you're likely arrested. Some kids eventually snap, and parents wonder why school shootings are a thing.
