I'm ok with police surveillance of public areas. The main difference between a police officer on foot doing the same is that you don't notice you are being watched and that the camera can travel over more distance more quickly. I'm assuming they delete much of the information they collect eventually. And I mean information, as in names from face recognition or license plates read etc, not necessarily the raw footage which may contain faces and license plates but in a relatively unusable form. Biggest problem there is that it's a waste of money much of the time.
