I love how the media is dramatizing the whole thing by referring to this system as a "Sniper Detector". If I'm not mistaken, the system detects gunshots in general and not just ones coming from a guy on a rooftop with a scoped high-powered rifle. Of course "sniper" is a glamour word and we all know how the media likes to glamourize things....
Anyway, as I said in the other thread, after a year of using the system the Broward Sheriff's Office has decided not to keep it. Too many false alarms. Apparently even a loud truck would set it off.
