It's not news that Washington, DC has issues surrounding gun violence. The City contracts with a firm called ShotSpotter to help it detect gunfire within the city. Urban researchers worked with the metro police department to analyze the data and found that ShotSpotter picked up 336 incidents of gunfire in DC during the school day (7 a.m. to 7 p.m.), over the 2011–12 school year. More than half of these incidents occurred within 1,000 feet of a public school.
This interactive feature mapped that data and offered more perspective on the places where these gunshots occured by using Google Streetview imagery. The feature also explored the sound of gunfire and explained how the technology behind ShotSpotter worked.
