Gunfire declined significantly in 2014 in American cities monitored by ShotSpotter, according to a study released recently by the company.
SST, which operates ShotSpotter, examined data in 28 cities that used the gunfire detection system in both 2013 and 2014. Instances of recorded gunfire dropped by 28.8 percent, according to the company.
All but two of the 28 cities saw reductions in their rates of gunfire.
ShotSpotter uses an array of microphones to record, identify and locate instances in which weapons are discharged. During 2014, it was used in 47 total cities.
The technology recorded 33,975 separate gunfire incidents nationwide in 2014, with 117,161 rounds fired. That breaks down to roughly 105 incidents per day.
