They didn't. This kind of shit is just no one thinking or paying attention and one sick idiot infiltrating to spread his perversion. Library hires a talent agency for entertainers. Talent agency has subcontractor entertainers they offer the jobs to. The contractors accept the work. Thats how this all works. The rainbowdildobuttmonkeyfaggot took the job and then decided it was a good idea to do this. This is on him. Should the talent agency be banned from further government contracts for the failure? Yep. Should the library have to vet performance entertainers before a showing? Yyyep. But this was this guy. The drag show shit is premeditated. This was just some pedo. Edit: apparently it was a trio of pedos. The agency contracted by the library, vision, contracted mandinga entertainment group for the performers. This fuck is part of that.
