That's nothing to do with school though, just youth. Kids who get into fights in the summer months away from school aren't sent to jail for it like adults. Being at or away from a school isn't a factor in that difference.
Children are forced to be around children in school. Outside they can avoid bullies most of the time.
Children don't decide what neighborhood they live in.
You’re right there’s sort of less freedom of escape in this environment. It’s like captive prey pretty much. Good insight.
