Spot on. Or how about the catering folks. Is EVERY soda can and wine bottle X-rayed to make sure it's soda and not something else ?
Special ops guys around the world make a living getting stuff into places it's hard to get stuff into. Not hard to imagine the same scenario with the folks who routinely bring stuff to the airplane.
So's methinks this is taking the illusion a bit too far. Unless they came upon some type of really unbalanced chap; but all kidding aside I don't know anyone I'd put into that category.
