In October of 2001, the idiot passenger-screeners at Phoenix Sky Harbor wouldn’t let Joe Foss take his Medal of Honor with him on a flight - they thought it was some sort of oriental martial art weapon.
Had they known he was awarded it for shooting down airplanes, they would probably have fainted dead away.
I cannot imagine a world where any person in a Security world would not know what a Medal of Honor looked like. Jeeez.
