At that time the cops had a policy of taking everyone who lived at the scene when drugs were found. If you lived with someone and drugs were found in a shared area you got arrested too, and all of a dorm room is shared space... That's why I reacted that way.
And he took me by surprise - a better introduction to one's new roommate might be "hello" rather than a question about storing your drugs.
