I'd prefer to focus my posts more on art and trash, but these days, that's not easy.
According to The Washington Post, the FBI, Britain, Canada, Australia, and New Zealand are cooperating to create recognition equipment coupled with a vast database of biometrics that would enable them to capture or identify images of people's irises at distances of up to 15 feet and faces from as far away as 200 yards. The database will also retain fingerprints and palm patterns, scars, and perhaps characteristic ways of walking and talking.
The FBI will also retain, upon request by employers, the fingerprints of employees who have undergone criminal background checks, "so the employers can be notified if employees 'have brushes with the law'" -- i.e., any contact with the law whatsoever, whether you’ve actually done anything wrong or not.
Director Lawrence A. Hornak of the West Virginia University Center for Identification Technology Research, which has been awarded a contract to further develop the system’s recognition capabilities, says, "The long-term goal" is "ubiquitous use" of biometrics. As WaPo put it, “[a] traveler may walk down an airport corridor and allow his face and iris images to be captured without ever stepping up to a kiosk and looking into a camera . . . .”

Another good reason to get yourself a gas mask, preferably with mirrored lenses -- and if you plan to protest, don't leave home without it.
