"Police say a camera's mere presence can deter criminals, while a crisp image can win a conviction. Police are asserting that they can catch crooks and respond better to emergencies by watching crime unfold in real time. They stress that the cameras have software that can block out spots where people still expect privacy, such as the windows of homes and hotel rooms. But critics say there's no evidence to support spending public money on cameras instead of traditional crime-fighting measures such as community policing programs and extra cops and street lighting."
