Lessons Learned Implementing Gunshot Detection Technology: Results of a Process Evaluation in Three Major Cities

Abstract This article describes the experiences and lessons learned from the implementation of gunshot detection technology (GDT) in three US cities. Data were derived from stakeholder interviews, community focus groups, and review of firearm-related criminal case files. Findings indicate that stakeholders view GDT to generate valuable investigative information, that officers are compliant with GDT response and protocols, and that residents accept GDT despite low levels of trust and confidence in the police. This article concludes with recommendations for future GDT implementations.
