Why not integrate backscatter scanners into airport walls, and have everyone pass by them without even knowing?
My understanding is you are not guaranteed privacy in a public place. And certainly court decisions have established the legality of extra invasive searches when people enter into an enclosed, "extra vulnerable" area (used to justify bag searches before boarding subways).
If people opposed to the scan are non the wiser they are being scanned, many of our problems in airports would be solved. The radiation received from these machines is minuscule compared to a chest x-ray, and even exceeded by the cosmic radiation the fliers receive when at high altitude.
I'm not advocating putting these scanners clandestinely into subway and rail stations, tunnels, bridges, building lobbies, roving vans.... yet. But why not use all tools at our disposal to make the terrorists' preferred target a little safer?
