Probable cause/Reasonable suspicion?

[TheBronzer]

Unless there is something you signed or provisions with your dorm they can't just search you.

If nothing is sticking out of the bag, the police officer can not search your items. The whole point of a search is if there is reasonable suspicion that it contains contraband (walking into a dorm room with a backpack shouldn't constitute reasonable suspicion). Further, patting someone down and searching them is allowed only for the officers protection, so they aren't going to Terry stop you (and then "stumble on your booze) because there is no reason to think you have a gun or a bomb.

Bottom line, your friend is a pussy and you should easily be able to sneak booze in your dorm. And don't carry it in a bitch ass purse either.

Since you are 20, you should have also moved off campus once you had the chance so you wouldnt have to deal with this [censored]
