It turns out that, while mere ticket-buying riff-raff like you have to get interrogated and irradiated just so you can go visit your Aunt Gertie in Steubenville, the behind-the-scenes Morlocks that actually run the joint get a free pass. In some major airports, as long as you don't have a letter of recommendation from ISIS in your resume or something, you apparently get to waltz through security without so much as a jaunty, "Top o' the morning, fuckwads," to the TSA agents.
"What the ...? Oh, it's Joe. Come on in."
Of course, this has the potential to backfire drastically ... as it did in Atlanta, where Delta Airlines employee Eugene Harvey was found to have smuggled 129 guns on to flights bound for New York. He wasn't even in security or any sector where being spotted with a gun every once in a while might not be so weird -- the dude was a baggage handler who expanded the "baggage" part to firearms, including an AK-47 and an AR-15. Oh, and some of them were loaded. Why risk getting caught with bullets when a little assault rifle is so inconspicuous?
And the money he saved on checked-baggage fees can go straight to his bail. Win-win!
