The Effects of ShotSpotter on Gun-Crime in Denver: An Impact Evaluation 

Marc L. Swatt, Craig D. Uchida, and Allison Q. Land


A team of researchers from Justice and Security Strategies working with the Denver Police Department have issued an evaluation of the ShotSpotter gunshot detection system. ShotSpotter technology was installed in four different locations and staggered over time. This allowed for comparison of gun crime trends in ShotSpotter and non-ShotSpotter locations. The results were mixed. Three of the locations experienced declines in gun crime. The fourth area did not experience a decline. During these same periods, there were mixed trends in non-ShotSpotter locations making it difficult to draw clear conclusions. The report included implications for future research on ShotSpotter.

Executive Summary

A team of researchers from Justice and Security Strategies working with the Denver Police Department have issued an evaluation of the coordinated Crime Gun Intelligence Center (CGIC) and PSN initiatives.  Denver’s PSN initiative leverages the CGIC to reduce gun crime by using forensic science nd data analysis to identify and prosecute shooters and their sources of gun crimes. The evaluation study included an assessment of the implementation of the CGIC as well as the impact on violent firearms crimes. Among the key findings were a near 24 percent reduction of violent crimes with a gun and a 38 percent reduction of robberies with a firearm. For more detail, see executive report here.

Sustaining Your PSN Initiative

Sustaining Your PSN Initiative's webinar addresses this issue – how do we sustain our PSN team, our PSN strategies, and the lessons we learn in PSN beyond the grant end date? We started thinking about this topic as we developed training to support effective implementation of PSN. The good news is that many of the same steps that lead to effective implementation are also key steps in sustaining your initiative over time. This is the focus of the Sustaining Your PSN Initiative webinar.
