Automated ballistic imaging technology is a potentially effective tool for improving the investigation and prosecution of violent crime involving guns. This technology enables crime laboratories and law enforcement agencies to link crimes committed with the same gun. Yet, in many localities, structural and procedural constraints hamper the potential effectiveness of ballistic imaging as an investigative tool. This study examines the impact of new personnel, processes, and technology on ballistic evidence processing productivity in the Stockton Police Department’s Firearms Unit. Using interrupted time series analysis, we examine the impact of several organizational changes on ballistic evidence processing productivity. Our findings demonstrate that the Stockton Police Department achieved rapid improvements in its ballistic evidence processing capacity. The study shows how introducing key organizational changes in a police department or a crime laboratory can generate disproportionate impacts on ballistic evidence processing productivity.
