Here’s another real world deployment of biometrics combined with video monitoring. It shows the short step from terrrorism concerns to monitoring anyone who disagrees with current Administration policies.
“With practice, you can recognize the video spies in the city of Washington, DC. To a casual observer, they resemble lampposts. Some of the cameras have a 360 degree view and magnify by a factor of 10-17. Some are equipped with night vision and can zoom in on a target well enough to read text on a written page or look into a building. Most are placed at locations that would not come to mind as primary terrorist targets: Smithsonian Castle, the U.S. Department of Labor, Dupont Circle, Union Station, Wisconsin Avenue, the Old Post Office, and the Banana Republic in Georgetown. Though the targets they view may not stand out as particularly vulnerable to terrorism, the cameras are placed strategically for the purpose of monitoring demonstrations and protests.”
