I guess the original poster thinks that police are more special than other citizens.
I have no problem with any place that prohibits firearms, as long as they provide adequate armed security. If the judge does not trust anyone armed in his court room with the exceptions of his courtroom security, well it's his venue.
CHI Health Event Center downtown, only allows police that they contract with for security to be armed, other police are not allowed to be armed on property. What's fair for one citizen should be fair for all.
