Baltimore police may join more than 30 other American cities in using an electronic gunshot detection system, reports the city’s Sun. Police have been testing a single gunshot sensor in East Baltimore. The devices can track gunfire to within 10 feet of the discharge. Linked with surveillance cameras, the alerts help officials quickly zero in on the area of a suspected shooting.
More than 30 cities use some form of the gunshot-sensing technology. In East Orange, N.J., police officials have lauded its gunshot detection system as the city has seen a 63 percent drop in shootings from 2003 to 2008. It’s not without flaws, however. The Boston Globe reported last year that of the more than 30,000 events recorded by the sensors, 98 percent were firecrackers or other loud noises. Police there credited only 10 arrests to the technology.
