"You won!"Ok, what she really said was that I was chosen randomly to be the subject of a further security inspection, It was a full public pat-down. Granted I was offered the option for a more private one, and they did bring me my bags after they had been x-rayed. But it was clear to everyone that I wasn't a risk and they were wasting their time.
I followed their instructions, pointed my toes and lifted my legs, just like they asked. And then I ran from one end of the Philadelphia airport to the other to catch my plane.
I'm too tired and jetlagged right now to write more, but I honestly don't see the deterrence in these random inspections. The Israeli profiling makes more sense.
