Argh! Due to a production glitch, my column today about the Philadelphia Police Department's surveillance camera system was accompanied by a photo that is NOT a Philly police camera. Rather, it is a red-light camera located on Roosevelt Boulevard. The systems are entirely different, and the red-light cameras are working just fine (as anyone who has gotten a red-light-generated ticket will attest!)
I hate when this happens. I apologize for such an embarassing error.
