A few terrific quotes:
I have the sinking feeling that you're defending us against a terrorist smart enough to develop his own liquid explosive, yet too stupid to read the rules on TSA's own website.and
This feels so much like "cover your [tail]" security: you're screening our shoes because everyone knows Richard Reid hid explosives in them, and you'll be raked over the coals if that particular plot ever happens again. But there are literally thousands of possible plots.Kip actually has half-decent answers to these questions.
So when does it end? The terrorists invented a particular tactic, and you're defending against it. But you're playing a game you can't win. You ban guns and bombs, so the terrorists use box cutters. You ban small blades and knitting needles, and they hide explosives in their shoes. You screen shoes, so they invent a liquid explosive. You restrict liquids, and they're going to do something else. The terrorists are going to look at what you're confiscating, and they're going to design a plot to bypass your security.
