Reminds me of the following scene from The Simpson's:
Homer: Not a bear in sight. The Bear Patrol is working like a charm!
Lisa: That’s specious reasoning, dad. By your logic, I could claim that this rock keeps tigers away.
Homer: Hmm. How does it work?
Lisa: It doesn’t work, it’s just a stupid rock!
Homer (after a moment's thought): Lisa, I want to buy your rock
It could well be that the ridiculous sums of money spent on "Homeland Security" (a phrase that creeps the fuck out of me) is indeed money well spent. But please allow me to posit that the terrorist threat is actually McCarthy-esque bogeyman. Nevertheless, if the people of the US truly want to be (as opposed to feel) more safe, the best policy just might be to refrain from meddling in other countries' affairs quite so much...
