My question involves civil rights in the State of: WI
I saw something happen at our public library that seemed rather questionable. A librarian went to a man who was using an internet computer and called him aside and said she needed to speak with him. They went to a place that was well within earshot of me, so I got to hear what was discussed. She told him that the library had received a complaint from somebody about him accusing him of "stalking", and that as a result, he was now banned from the public library for one year. Of course, he protested this (rather loudly) and then the police got called on him. I don't know what happened after that, but it got me wondering about the legality of it.
If a facility such as a public library is a publicly funded facility, how could a single person running that facility ban a member of the public from having access to it based on a mere accusation? I could understand a person having the police called on them and an investigation done to determine whether to arrest them or file charges. That way of going about it would make sense. But banning someone from the library based on an accusation alone would seem no different from banning someone from a public park, or even sections of town for the same reason. If a place is public, then how can any member of the public be banned from it?
