Why would terrorists even bother with this when they can just enter the NoS with a gun and have a 70% chance of getting it through? Or get a job with an airside vendor and have a 100% chance of getting the gun through?
I recently heard an AFSer insist that everyone and everything airside--including employees and goods destined for airside vendors--is screened by the TSA. Is there an ounce of truth in this? Did the guy behind the counter at the ATL Pizza Hut go through the TSA before getting to his workplace? Is every dolly stacked with Coke screened for prohibited items? Anyone who watches _Breaking Bad_ knows that a dolly stacked with Coke is a great hiding place.
