What country are you in? You can't loose criminal rights just because you live somewhere that is hard on crime. Unless someone brought the cops through, or he had a warrent, or there were some extenuating circumstances (doesn't sound like there were) then he can't search your place, I don't care care if you live on a private campus, next to the police station, or anywhere... in the U.S. that is. Like I said, probobly won't get your bong back... but sure sounds like an illegal search to me.
