I have a better solution, it is much cheaper and way better than wasting money on these stupid scanners and invasive pat downs. I don't understand why our stupid gov't has to look high tech when there has always been a low tech solution to detecting a hidden explosive. The gov't could have spent the money on training explosive material sniffing dogs and deploy them at the security lines. They can detect explosives from miles away, and even hidden places, heck the military has been using dogs for that kind of work for years, makes perfect sense to use them at the airports for the same purpose. You place them right at the security point entrance, if they don't sense anything, then you proceed to the metal detector as usual, way better solution and less expensive, plus no patdowns, problem solved......
