Don't feel any safer with cameras around. Do feel watched, and, I just don't like it. I am entitled to some privacy outside too.
In shops they do make sense.
How are you entitled to privacy in public?
OK, lets state it different, in public, I can be seen, by people who I should be able to see too. So, if I want a moment, just for me, I can know where to go, and sit on my own on a bench, or at the stairs of a building or so. A camera is not a mutual thing.
Maybe I would find it less hard if there was a display next to every camera, showing the people watching the images.
