It's probably worth noting at this point that TSA Backlash Week isn't a conservative or liberal phenomenon. It's got just about everybody angry, with nobody outside the TSA itself offering much in the way of a vigorous defense of body scanners and patdown. So it's interesting to note the Wall Street Journal is publishing a critique of the TSA, a piece from Wired's Noah Schachtman.
Money quote: "But the larger question is whether the TSA's tech-centric approach to security makes any sense at all. Even the most modest of us would probably agree to a brief flash of quasi-nudity if it would really ensure a safe flight. That's not the deal the TSA is offering. Instead, the agency is asking for Rolando Negrin-style revelations in exchange for incremental, uncertain security improvements against particular kinds of concealed weapons."
