The problem with this stuff is that it cuts both ways. You think you are protected by these surveillance schemes, but then your local government starts tolerating petty crimes like vandalism, auto theft, vagrancy, and shoplifting because it centralizes their role in "managing" (read: extracting value from) it, offering protection to favoured constituencies in exchange for support, and then when you want to shovel a tent off your property, paint over grafitti, or discourage a shoplifter, those cameras neutralize you because you can't take the risk of being charged because you actually have something to lose. Cameras don't stop criminals, they just neutralize law abiding residents from discouraging threats to themselves and their community.
