Detroit City Council narrowly voted 5–4 to renew a contract with SoundThinking for its ShotSpotter gunshot detection system until March 2027. Critics cited high costs, privacy concerns, and lack of proven effectiveness, while supporters highlighted successful cases like a 2023 incident where the system led to a gunshot victim's rescue.

Detroit City Council narrowly approved a $2.1 million extension of its contract with SoundThinking Inc. for ShotSpotter gunshot detection technology through March 2027. The 5-4 vote followed a divided debate, with critics questioning the technology's effectiveness and cost, while supporters emphasized its role in reducing gun violence.

Detroit Police Department is considering expanding gunshot detection technology ShotSpotter into downtown and southwest areas through a new Request for Proposal (RFP).

The Detroit Police Chief and representatives did not mention the expansion during recent council hearings.

Chicago alderpeople are pressuring city officials over delays in replacing ShotSpotter, a gunshot detection system canceled in September 2024. Despite a February 2025 request for proposals and nine vendor responses, the selection process remains ongoing, sparking frustration among lawmakers.

The Pennsylvania Supreme Court upheld the arrest of Jamar Foster in Pittsburgh based on ShotSpotter gunfire detection system alerts, despite civil rights concerns about the technology's reliability. The 5-2 decision found reasonable suspicion for the arrest under the 'totality of the circumstances,' including late-night alerts, rapid police response, and Foster's evasive behavior. Two justices criticized the ruling for failing to address the system's reliability and the relevance of proximity to a high-crime area.

Cambridge, Massachusetts voted to end its contract with ShotSpotter, a gunshot detection system used by police, citing concerns about reliability, false positives, and potential links to federal immigration enforcement. The decision follows similar action by Chicago in February 2024 and reflects growing skepticism about the technology among some cities. The city has 90 days to discontinue use and remove the acoustic sensors from neighborhoods.
