This document discusses gunshot detection technology and its benefits for law enforcement. It begins with an overview of topics to be covered, including the purpose of gunshot detection technology, its benefits for law enforcement, and how it can help cash-strapped police departments. It then discusses how the technology works by detecting and locating gunshots to guide police response. Case studies show how gunshot detection technology has helped police in cities like Washington D.C. and Los Angeles locate gun crime victims and make arrests. However, the high costs of the technology have led some cities to reject it during economic recessions. The document concludes by arguing that gunshot detection is still worth investing in to improve public safety.
