Not by yourself man, some officers do know the law but most do not. I was at Ga.Arms the other day and a guy fresh out of the Air Force was telling the man behind the counter that he had asked Cobb Co. Police, a lawyer, and a judge if he needed to have a GWL to open carry, ALL OF EM' told him no! I told him they were all wrong and he was gonna be in deep doo doo if he listened to that crap and refered him to gacarry.org for the REAL TRUTH!
Fresh out of the AF, yes, he needs one like anyone else. In the AF, no, he doesn't. I imagine whoever he asked thought he was still in.
