CrazedWalrus writes "Philadelphia police recently captured a serial killer with the help of a combination of Homeland Security and private surveillance cameras. Police examined video from 50 different cameras and pieced together relevant footage from 12 of them, and eventually were able to identify the murderer. Once caught, he confessed to several other murders spanning the past eight years. Without these cameras this killer would probably be stalking the streets of Philadelphia today. With results like that, is there really a good basis for argument against these cameras?"
