There's a lot of fuss about naked body scanners and intrusive pat-downs at the moment, and rightly so. However, there's also an elephant in the room that nobody is talking about so I'm going to.
The main point of these precautions is to lower the probability of a terrorist getting a bomb onto an airplane and setting it off.
But all a terrorist has to do is to stuff a bag of explosives up their ass or put it into their vagina and then opt for the pat-down. The pat down isn't going to find it.
