So, if me and my four buddies just want to sleep in the gym overnight- without disturbing school functions of course, then it's ok?

School grounds outside of the building should be treated essentially the same as park grounds. Park grounds are open to the public during the day. Comparing being outside in a parklike setting to being inside a secured building is just silly.

I assume the assistant principal has the authority to order students off school property when the school is closed- probably even when it's open.
