Just because you're paranoid doesn't mean they aren't after you

Ars Technica reports on a new Georgetown study:

"Half of American adults are in a face-recognition database.. By using face recognition to scan the faces on 26 states' driver's license and ID photos, police and the FBI have basically enrolled half of all adults in a massive virtual line-up. This has never been done for fingerprints or DNA. ... 

At least five major police departments, including those in Chicago, Dallas, and Los Angeles, either claimed to run real-time face recognition off of street cameras, bought technology that can do so, or expressed an interest in buying it. ...

Police departments have little oversight of their databases and don't audit them for misuse."

The Baltimore Sun writes: "the American Civil Liberties Union in California released documents last week showing the system was used to monitor protesters during the unrest and rioting in Baltimore last year."
