What does the science say about ShotSpotter?

People in this story

Chicago Justice Project, July 2024

In a first-of-its-kind independent analysis of the effectiveness of ShotSpotter, the science says the technology does not lead to more arrests and convictions for gun crimes and does not reduce these crimes in the areas where it is deployed. The study examined the impact of ShotSpotter in Chicago and Kansas City. To understand the science more deeply, we sat down with the study’s first author, Dr. Eric Piza, who is a Professor of Criminology and Criminal Justice, Director of Crime Analysis Initiatives, and Co-Director of the Crime Prevention Lab at Northeastern University.

The study does uncover that ShotSpotter positively impacted response times, the location of victims, and the recovery of evidence from crime scenes. While this all sounds great, it is not even remotely reflective of the criminological gains promised by SoundThinking, the company that owns the technology. The original sales pitch promised more arrests for gun crimes and convictions and, thus, a reduction in gun violence. None of these promises have come to fruition.
