I've got a buddy who's an Air Marshal. He's a tough guy and a good shooter. You should all be happy that he is in the air. I am non-LE but carry daily and have for years. I try to spot carriers and the airport/airline procedures that identify the LEO's with firearms. I send the info to my buddy. I send it not to "out them" but to help them. I figure if I can spot them, the really well trained bad guys can. I want them hidden in plain sight.
