allgov.com The District of Columbia, parts of which have been plagued by poverty and crime, has experienced so much gunfire that it averaged at least one gunshot every two hours over the past eight years. This fact was derived from an analysis of data culled by The Washington Post after reviewing police records of a gunfire surveillance network known as ShotSpotter. Consisting of rooftop sensors mounted on buildings and light poles through the city, ShotSpotter notes every time the sound of firearms being discharged is detected. Those sounds are analyzed by a computer and tracked to within yards of their source location—a process that takes less than 40 seconds per incident. Personnel monitoring the system notify police in the field, who then speed to the location. to read more click here: allgov.com
