You're wrong here Bernie. There is nothing wrong with security camera's in public places. If you are not doing something illegal, you have nothing to worry about. So many camera's, so much tape/hd recording, so little time. The worst a person would have to worry...is that they'd be caught on tape cheating on their spouse. The fact is, the camera's that existed in Boston, allowed these two to be tracked down fast, before they could plant the rest of the bombs they had. ETC.Yes, a loss of civil liberties is an issue. But security cameras in highly public areas...are a tool that has helped in this instance.
I agree with the Anon above. Security cameras in London, U.K. have been a great tool in preventing and fighting crime.
