I flew yesterday and found a rifle bullet+cartridge on the "secure" side of the TSA checkpoint. Yet somehow the gift-wrapped paperbacks in my checked luggage were deemed suspicious and unwrapped. Useless fools.
The rifle cartridge is obviously on their contraband list, so it should have been caught. Someone probably brought it through accidentally. .22 LR?
Rather, this seems like a perfect example of the self-perpetuation suggested in the article. It takes a while, so there's a line, it look very meticulous and the victim isn't going to complain, or he might risk finding himself on a do-not-fly or do-harass list.
