At first I LOL WTF, but then I remembered how far down the societal ladder goes. Some schools have a constant problem with vandalism. Knowing which kids are in the halls at what time will help narrow down which shithead ripped the sink off the wall.
At least in schools that information has little consequence, while at-will work ensures this is just the 5 lines needed for the Cardinal to hang a man with.
