Jim Fallows lays out the case against full-body scanning:
But anyone who’s ever thought about terrorist movements realizes that the real damage is indirect — it’s the fear they induce, the (over) reaction they provoke, the costs they impose as a society tries to guard against repetition. That’s what Osama bin Laden noted in a tape after 9/11 — that on the cheap, his attackers had not simply killed 3,000 people but induced a response that will cost the U.S. trillions of dollars over a decade or more (if the costs of war in Iraq are included, as they should be).
