<< Personally in the dorms, I considered everything in there expendable. Period. Sure it may not be stolen but having a can of coke spilled on the back of the tv will have just about the same effect: one tv that you cannot use. Beyond that, get renter's insurance. Just remember, you cannot control who your roommate allows in the room or your roommate's actions. (assuming you have a roommate) >>
A dorm room definitely isn't a place to have terribly valuable stuff laying around. I'd say leave it home. You're not going to get the to let you change the lock, and as someone said, if you show the RA you can pick a lock, then if someone's lock gets picked, guess who they're going to come after first...
And, as someone else also said, you can't control your roommate. I had a slacker roommate whose daily schedule was like this:
2:00PM: Get up and go to the bathroom.
2:20PM: Go back to sleep.
3:00PM-Midnight: Hang out in the room down the hall smoking up, drinking, playing PSX, wondering why his grades are so much worse than everyone who actually shows up for class.
Midnight-3:00AM: Go out somewhere else to drink and smoke.
Repeat ad nauseum and never ONCE lock the door during this time....or even take the key with you.
YMMV, but I'd say if you're afraid it's going to be stolen, you probably don't want it there.
