When I was a freshman, our room was raided by an OSI guy who we thought was a janitor. We were interrogated individually, subjected to strip search, and basically it was the scariest thing I'd ever undergone.
Yes they found weed. One of my roommates, a total doosh, had put all of us in danger. At least he copped to it.
That place has changed so much, I barely recognize it any more. It makes me sad that it has come to this... coercing cadets in trouble to become street informants.
