New Orleans is installing a sophisticated crime-fighting system of bulletproof cameras, each capable of eyeing an eight-block area. So far, about 240 of the proposed 1,000 cameras are in operation.
New Orleans officials say their system has plenty of safeguards against abuse. Cameras are not routinely monitored and video is stored for a brief period, to be watched if a crime is reported. Only a few officers have access to the video and they look at it only in response to a specific report, officials said.
