Can you charge for criminal trespassing for something that boils down to just being internal policy? The school can't anyone for this. Literally the only thing that they can do is expel a currently enrolled student. So again, it is mind boggling that they'd even bother going through all this for a policy that will almost literally affect no one. Someone who isn't a student isn't going to give a crap. A student who wants to commit a school shooting CERTAINLY can't expect to go back to classes next semester.

This must just be for the sake of the parents. Pretty nice of the school to go out of their way to pretend to protect all those legal adults for the worried parents out there.
