Let me assure you of one thing - if they ask you to leave and you refuse you will be arrested. Please make no mistake about that and don't play that card unless you want to be the "test case" regarding the legality of this issue. If you do great - and I hope you prevail, but don't cry uncle when the cuffs come out. Once that happens you're next stop will be at Lew Sterrett.They may or may not arrest you if you do not leave, they count on us believing they will.
Again, I hope that the TSRA (of which I've been a Life Member for many years) can petition the Texas AG for a ruling on this so that no one has to challenge it through the criminal court system. (Charles, I don't even know if that can be done. I know the DAs and County Attorneys can do it but I'm not sure if private parties can do the same.) And even if CHL holders got a favorable ruling from the AG that doesn't prevent government entities from taking the AG to court if they don't like the outcome. Probably the only way this will get resolved is for the legislature to clarify the language of this, or for a case law ruling to come down.
