Officer Nasty works security at the library. He doesn’t wait for trouble to happen or for someone to ask him for help. Instead, he constantly patrols the whole place looking for people who may be breaking the rules, so he can put them out. He walks up and down the narrow aisles of the computer center to see what you have on your screen. He comes into the men’s room hoping to catch someone in the act — act of what, I can’t imagine. You get the picture.
