We still think there's an argument to be made that TSA should have started with this kind of technology, and that the agency was swayed into wasting money in part by scanner lobbyists who flooded DC. It seems difficult to defend spending billions and billions of dollars, and changing airports' security protocols over and over, for machines that were only going to be used for a couple of years. Someone should have said "it's likely that these will create a huge public backlash, and that we'll have to almost immediately replace them, and so maybe we should skip ahead to something we'll be able to use."
But why dwell on the past, when we could be focusing on the positives? Some day, right here in America, people will be able to walk through airports without having to suffer intrusive and potentially humiliating security checks. Sure that seems like a dream today, because who could possibly imagine a country where average citizens aren't searched like criminals just because they want to get on an airplane? But some day it just might happen.
