When it comes to profiling by race, it just cannot work. You'd have much better results profiling by actions, demeanor, suspicious activity. You could put an infrared camera above the security gates and see if anyone is unusually warm (nervousness -- blood flow to the surface, etc). However, to think that most Arab-Americans should be hassled more often than others because of a few sick individuals is wrong. I guarantee the moment they spend more time and resources checking Arabs, a black man or white man will hijack a plane. It is just plain stupid to assume that "skin color = mode of behavior" Check more obvious things besides color and security will be much more successful at pulling aside the potential bad guys. Like I said earlier, some type of stress sensing camera would be far more beneficial than sampling by skin color.
Quote from aphexcoil "some type of stress sensing camera " Out of curiosity does such a thing even exist?
Not that I know of, but I don't see why it would be hard to research and build one that works fairly well.
