Before Ky. got a concealed carry law, a friend of mine wanted to show his uzi subgun to some people that were in a restaurant. He brought it in (unloaded) and layed it down on the table that they were all at. Someone in the establishment called the police and then informed him the police were coming. Fearing what might happen if caught walking out of the restaurant with an uzi, he decided to stay put until the police arrived. The police arrived and locked him up for disorderly conduct and confiscated his subgun.
Another friend of ours (a lawyer) defended him and got the charge dismissed and the uzi returned to him, as no law had been broken (at that time).
As we all said, the only thing he was guilty of was poor judgement.
A year later one of the officers that responded to the restaurant, locked my friend up in front of the same restaurant for DUI.
Now that we have a concealed carry law, buisnesses that don't want firearms on the premises must post a sign to that effect, and a person ignoring that sign would be guilty of criminal tresspass 3rd degree if refusing to leave after being asked to leave or remove the weapon.
