ShotSpotters are at the center of a debate over their cost

Minneapolis is debating whether to continue funding ShotSpotter, a gunshot detection system that alerts police to shootings, after spending over $3 million and facing criticism over its effectiveness. The Minneapolis Police Department requested a three-year extension, while critics like Council member Robin Wonsley argue the technology has not improved crime-solving rates, which remain low compared to other cities like St. Paul." "article": "Minneapolis is reconsidering its $3 million investment in ShotSpotter, a gunshot detection system that uses acoustic sensors to alert police to shootings. The technology, deployed in North and South Minneapolis, is supported by the Minneapolis Police Department, which requested a three-year extension and expansion to more areas. Supporters, including Council member LaTrisha Vetaw, argue the system saves lives by helping officers respond faster and locate victims. Critics, however, question its value. Council member Robin Wonsley pointed out that Minneapolis’ homicide and nonfatal shooting clearance rates have remained among the worst in the country over 12 years. Chicago ended its ShotSpotter program in 2024, citing improved response times without the technology, though a University of Chicago study attributed a 4-minute reduction in response times to broader reforms rather than ShotSpotter alone. St. Paul, which does not use ShotSpotter, has achieved a 73% clearance rate for nonfatal shootings through specialized units like its non-fatal shooting team. Minneapolis recently launched a similar initiative, but Mayor Frey noted that the city’s 2025 homicide clearance rate was 80%, while nonfatal shootings remained under 50%. The Minneapolis City Council will revisit the issue after the city auditor completes a study on ShotSpotter’s effectiveness. For now, the police department has proposed a one-year extension while awaiting the audit’s findings. The debate highlights broader concerns about balancing technology investments with alternative public safety strategies.
