I understand your point, but I disagree. I don't see how this is a "difficult challenge" at all. Yes, it is easy to kick someone out of the library - but for being loud, boisterous, destructive, whatever. But CHILD *advertiser censored*?!? Its gross, its certainly not conducive to "free learning" and to top it off, its illegal. I don't think the library would be swarmed by LE. The librarian can call the police, kick out the offender and the LE can arrest him outside of the library. The offender wouldn't even have to know that it was the librarian that called, it could have been a patron of the library. I would hope that this case is the exception to the rule and that libraries do not "let alot go that should be reported and is illegal". But this is all just MHO.
