Here is an idea. Offer everone as they approach the plane a piece of bacon. If they eat it, they board, if not they get scanned, wanned, patted, orifice searched, fillings Xrayed, Colonoscopied, held for 72 hours while every bit of crap that comes out is scanned, tested chemically, and Xrayed. Then they can board.
What if they are Jewish?
If someone is willing to put a bomb up their butt, don’t you think they would also be willing to eat a piece of bacon to complete their mission?
