Abstract
We apply the microsynthetic control method to evaluate the gun violence prevention effect of gunshot detection technology (GDT) in Kansas City, MO. We measure the influence of GDT on process measures (ballistic evidence collection and gun recoveries) and outcome measures (shots fired calls for service, non-fatal shootings, fatal shootings, and aggravated assaults and robberies committed with a firearm). The GDT system was associated with higher levels of ballistic evidence collection in the GDT target area and surrounding catchment area, higher levels of gun recoveries in the surrounding catchment area, and lower levels of shots fired calls for service in the GDT target area. The GDT system did not influence any of the gun violence categories involving confirmed victims (non-fatal shootings, fatal shootings, and aggravated assaults and robberies committed with a firearm).
期刊介绍:
Criminology & Public Policy is interdisciplinary in nature, devoted to policy discussions of criminology research findings. Focusing on the study of criminal justice policy and practice, the central objective of the journal is to strengthen the role of research findings in the formulation of crime and justice policy by publishing empirically based, policy focused articles.
