First of all, the procedures may be modified, but they're not going to change appreciably. Body scans and pat-downs are here to stay, coming to an airport near you. And we haven't even started with train stations and metros yet.
Second of all, where is this "it accomplishes nothing" propaganda coming from? Do you think repeating it enough times makes it true? Please show us the secret memos wherein a consensus of experts concludes that body-scans and pat-downs have no value, yet the government pushes forward with its highly cynical plan to provide the flying public with nothing more than warm fuzzies, at a cost of billions.
I'm the last person to deny that politicians preach to the lowest common denominator among us. And I've seen plenty of evidence of cases where politics trumps science. But engaging in a multi-year, multi-administration, multi-billion-dollar boondoggle to con the American public into a false sense of safety is tin-foil-hat material. Again, where's the evidence?
