| 520 | |a Objectives The primary aim of this study is to provide an evaluation of St. Louis’ Acoustic Gunshot Detection System’s (AGDS) ability to reduce gun violence. Methods The study design is a quasi-experimental longitudinal panel study. We measure a variety of gun-related offenses across multiple treatment and control neighborhoods using a difference-in-difference approach. Because treatment neighborhoods were added to the experiment over time, changing experimental conditions, three separate study periods were examined. Results Results indicate AGDS has a mixed relationship to police response time and does not significantly reduce violent crime levels in any of the study periods. We do find consistent and substantial reductions (around 30%) in citizen-initiated calls for service for shots fired, but once new calls for AGDS are added, an overall 80% increase in gunshot responses is found. Conclusions Although the study is limited to one city, results indicate AGDS may be of little benefit to police agencies with a pre-existing high call volume. Our results indicate no reductions in serious violent crimes, yet AGDS increases demands on police resources. | ||
