Sure. I could tell you stuff about porn and the public terminals. For example, the Dean of library established a policy that prohibited us from "hassling" anyone viewing "adult material" regardless of age. I am not kidding. Eventually, the policy changed to allow us to kick minors off terminals if they were viewing porn.
Tell me the true stories of what you witness, what policies they make you follow with with you disagree, why, what's the worst stuff that happens in the library, are you allowed to call the police, etc. No need to respond here. Take your time and let us know what's what with your situation, and I'll post it up on my group's web for all to see. Who knows - you could help someone else in the same situation.
