Who carries?

In oklahoma if you carry in a resteraunt or store that has a no guns sign they just ask you to leave and go to the cops if they feel like filling out lots of paper work and sending it off and all that hassle so they typically just ask you to leave or get rid of the gun. However with open carry coming to us in november were going to see a change in the signs to say something like concealed carry only or something like that. Its because of the shooting in texas a few years ago. A man and his wife were eatingin a resteraunt and he left his gun in the truck like he was supposed to . A man came in and started shooting and killed his wife. He sued the resteraunt for taking away his right to bear arms and protect himself and wife. He won several million dollars and then said "this money wont bring my wife back and i dont even plan to keep it." He wanted them to know what taking away his rights did. He then started giving all the money away.
