I was open carrying at the Walmart in Canton and as my wife and I were loading the groceries into our vehicle, a man starts walking towards us from a vehicle across from us. He said he was an officer with some department, but I didn't quite catch what he said. He told me that I needed to conceal my weapon, as I was currently breaking the law. I told him he was mistaken, as Georgia's Weapon Carry License does not specify the method of carry, so it can be carried either open or concealed. He told me I was wrong and I needed to conceal my weapon right now, and threatened to get his badge out of his vehicle. I tried to show him my license, but he started to walk back towards his vehicle like he had no interest in what my license actually said. I told him again that he was wrong and didn't know the law, but he was persistent, believing he was right. I told him to get his badge, but all he did was get in his vehicle and drive off. My guess is he was just one of those anti-gunners trying to intimidate me, upset someone has the gall to openly carry in a public place, like Walmart. I can only hope that he attempts to verify what he thought is law and gets a reality check.
