My school does that for the "athletic code". Good thing Lacrosse here is a club sport, otherwise our entire team wouldn't be able to play. They did a bust at some big party that I was at, but I peaced quick and got away from the police. So later, my tennis coach (school sport, so they can do shit about it) calls me in, and says I was in photos and they are going to bust me. So I asked to see the photos, just to be sure, and they were just doing that to people other kids said were there. So I got out free.
