Refresher: TPC 30.05 lists a defense to prosecution when a condition of entry is that entry with a handgun is prohibited and the actor has a CHL. TPC 30.06 doesn't apply when the property is owned or leased by a governmental entity. The situation I'm thinking of is that you're carrying a concealed handgun into a government building (one that isn't a legislated no carry zone like a courthouse) and it is discovered that you have a concealed handgun (metal detector, virtual strip search, patdown/frisk, printing, etc), such as at Galveston mardi gras event on the strand. Say you get a boneheaded cop that doesn't get that says he won't let you come in or stay with a gun no matter what. Is there any law that can be cited to justify his denial of your entry? Can a cop (lawfully) just keep you off a street or out of a tax office because he doesn't want you there? Do you have any recourse on the spot, or are you stuck with trying to get a DA to file on him for official oppression? I'm pretty sure there's no civil right action for violations of the penal code.
