@w7voa It is remarkably stupid to carry a firearm into an airport, but I have to confess that I habitually carry a pocket knife (or a Leatherman multitool, which has a blade), I have forgotten to leave it at home when travelling, and thus have had to trash or surrender it at a checkpoint. I am that absentminded. So I can believe the "concealed carry" freaks are both stupid and absentminded.
