"Each time the terrorists try a tactic, the specific tactic is blocked by security procedures post hoc. So the terrorists try a new tactic. We then block that.
We had hijackers with pistols, we introduced metal detectors. Then there were hold luggage bombs, so we started screening hold luggage one way and another. Then the hijackers used little knives, so we confiscated nail-clippers. Next we had the shoe-bomber, so now we all have to have our shoes inspected.
And the latest is liquid explosive in bottles, so we ban bottles of water.
I don't know about the rest of you, but I'm dreading the eventuality of the underwear bomber.'
It's the foreskin bomber who worries me......
