I know, there will be massive fights that quite literally bust holes in buildings and almost (and sometimes truly) kill students but all that happens is the tired school nurse just fixing them up (if they're alive) and sending them out again? And it's worse when it's not even underground or anything, just MC tries to walk down one (1) hallway, gets beat up twice, goes to class with a ripped up face and bloody nose and the teacher just doesn't even comment.
At my old, massive public middle school, there was a fight. Just the one, between just two students, without that many eye-witnesses. By the end of the day, everyone in the grade knew about it, knew the reasons behind it, the police got involved, and both students faced suspension for I think two weeks. But students in these schools just casually murder/beat to a bleeding pulp other students within the campus and no one bats an eye?
