An Evaluation of the Baltimore Police Department’s Crime Gun Intelligence Center
By Marc L. Swatt, Craig D. Uchida, Anna M. Goedert, and Alese Wooditch
Gun violence remains a challenging problem for law enforcement agencies across the country. According to the Centers for Disease Control (CDC, 2023), there were 20,958 firearm homicide deaths across the United States in 2021 resulting in a rate of 6.3 per 100,000 residents. This rate understates the problem, as the risk for firearm homicide is not evenly distributed and certain segments of the population have a considerably higher risk of firearm homicide victimization. For example, for 15-19-year-old Black males, the rate of firearm homicide death is 98.9 per 100,000 residents and for 20-24-year-old Black males, the rate is 134.4 per 100,000 residents (CDC, 2023). Further, firearm homicide is concentrated within impoverished areas within cities (Kravitz-Wirtz, Bruns, Aubel, Zhang, & Buggs, 2022). Recent research suggests that firearm violence has increased in the aftermath of the COVID-19 pandemic (Kegler, Simon, Zwald, Chen, Mercy, Jones, et al. 2022; McDonald, Mohler, & Brantingham, 2022). While the causes of firearm homicide are complex and involve both risk and protective factors (see American Psychological Association, 2013; Gaylord-Harden, Alli, Davis-Stober, & Henderson, 2022; Mattson, Sigel, & Mercado, 2020; Pardini, Beardslee, Docherty, Shubert, & Mulvey, 2020), there are strategies that law enforcement can adopt to reduce the prevalence of firearm violence (see Braga, Turchan, Papachristos, & Hureau, 2019; Braga, Weisburd, & Turchan, 2019; Uchida & Swatt, 2013). Recently, law enforcement agencies have sought to leverage forensic evidence from gun discharge events to improve gun violence suppression efforts. Traditionally, firearm forensic evidence – namely retrieved firearms and spent casings – were used mainly to enhance prosecutorial efforts at obtaining convictions. However, by rapidly entering and retrieving information from the ATF’s National Integrated Ballistics Information Network (NIBIN) and electronic gun tracing database (eTrace), law enforcement can proactively use this information to identify linkages between seemingly disparate cases to apprehend likely shooters and disrupt gun trafficking networks (see Pierce, Braga, Hyatt, & Koper, 2004). To maximize the efficacy of this strategy, several agencies have been adopting coordinated interagency firearm enforcement programs – Crime Gun Intelligence Centers. The Baltimore Police Department (BPD) is one of 46 agencies across the country that received funding from the Bureau of Justice Assistance (BJA) to set up a CGIC. In 2018, BPD planned its CGIC and over the next five years implemented key components of it. Justice & Security Strategies, Inc. (JSS) served as the research partner on the grant and evaluated the program. This report details the results of this evaluation effort. In this chapter, we first discuss the CGIC concept, how CGICs can decrease gun violence and the results of CGIC evaluations. In the second chapter, we discuss the City of Baltimore, the BPD, the implementation of CGIC, and the unique challenges facing this implementation to provide context for our findings. In the third chapter, we discuss the results of the process evaluation for CGIC and discuss CGIC activities, challenges, and successes. The fourth chapter presents the results of the impact evaluation and examines whether CGIC was successful at reducing violent gun crime. The final chapter provides additional discussion of the conclusions of this research and provides several recommendations to BPD for the continuation of CGIC.
