IDK about detention, but I've nearly gotten sent to the principal several times for going to my car (which is parked in an area considered OFF campus). Now this is only forbidden during the FIRST break. During lunch, you're allowed to leave campus. I think it's ridiculous! The lockers are easy to break into, and I refuse to park in the school parking lot where my car will get dinged up and where I have to wait for an eternity to get out!
