ˀThe Chicago Office of the Inspector General (OIG) has released a highly critical report on the Chicago Police Department’s use of ShotSpotter, a surveillance technology that relies on a combination of artificial intelligence and human “acoustic experts” to purportedly identify and locate gunshots based on a network of high-powered microphones located on some of the city’s streets. The OIG report finds that “police responses to ShotSpotter alerts rarely produce evidence of a gun-related crime, rarely give rise to investigatory stops, and even less frequently lead to the recovery of gun crime-related evidence during an investigatory stop.” This indicates that the technology is ineffective at fighting gun crime and inaccurate. This finding is based on the OIG’s quantitative analysis of more than 50,000 records over a 17-month period from the Chicago Police Department (CPD) and the city’s 911 dispatch center.
