CHICAGO—Only 9 percent of ShotSpotter alerts responded to by Chicago police officers led to evidence of gun crimes, according to an August report by the City of Chicago’s Office of Inspector General (OIG).
The ShotSpotter system, developed by the California-based company ShotSpotter, uses acoustic sensors to detect gunshots in real-time for faster and more precise police responses. A total of 119 U.S. cities use the system, including New York, San Francisco, and Minneapolis.
