Cameras' View Expands

This might explain why we've seen so many red-light cameras with black garbage bags over them:

• Chicago’s switch to a new red-light camera vendor that uses radar technology will allow hundreds of cameras installed at busy intersections to pan in all directions — worrying civil libertarians who fear an invasion of privacy.
  
  Adam Schwartz, a senior attorney for the American Civil Liberties Union of Illinois, said the Chicago Police Department should use the 360-degree panning technology only when there’s “suspicion of criminal activity.”
  
  That means police should not track individuals on the street unless they’re searching for a “particular suspect,” Schwartz said.

That means if you can see the camera, it can likely see you. Nice to know.
