The Detroit City Council voted 5-4 to renew its contract with SoundThinking for the ShotSpotter gunshot detection system, approving roughly $2.1 million in funding to keep the network operating through the end of March 2027.
The narrow decision followed hours of public testimony and council debate over cost, accuracy and privacy. Supporters said the system helps police find victims and shooting scenes that might otherwise go unreported; critics questioned its effectiveness and expressed civil liberties concerns.
ShotSpotter: Council vote and contract details
Council members approved the renewal by a 5-4 margin, extending the existing agreement with SoundThinking. City officials described the cost of the extension as about $2.1 million and said the coverage targets specific precincts.
Council President James Tate, who has supported ShotSpotter in prior votes, said he opposed the most recent amendment over the price. “I have a challenge with that dollar amount. It’s not about the technology,” Tate told colleagues during the hearing, according to reporting from the meeting.
How ShotSpotter works
ShotSpotter uses a network of acoustic sensors mounted in public areas to detect sounds consistent with gunfire. When its algorithms flag a likely gunshot, the system generates an alert that can be routed to police dispatchers and investigators with time and location data.
The technology is designed to identify incidents that do not generate 911 calls, potentially speeding officer response. Its performance depends on sensor placement, calibration and subsequent human review of alerts.
Arguments for and against the renewal
Detroit police officials and other proponents highlighted cases they say show ShotSpotter’s value. Assistant Chief Franklin Hayes told the council that a ShotSpotter alert on the city’s west side led officers to a gunshot victim who was found alive in an incident where no one had called 911.
Opponents pointed to cost, false alerts and privacy risks. Councilmember Gabriela Santiago-Romero said she had not seen data demonstrating the system’s effectiveness relative to its price and raised questions about data protections. “Frankly, I still have not heard enough support from the public, have not seen data that shows that this is working for the cost and that it’s actually protecting our information,” she said at the hearing.
Gabrielle Dresner, a policy strategist with the ACLU of Michigan, testified against renewing the contract, warning that false alerts can prompt unnecessary police responses and that acoustic microphones monitoring public spaces raise surveillance concerns. Dresner said those outcomes can reinforce harmful policing patterns for minority communities.
Local impact, cost scrutiny and history
Detroit began deploying ShotSpotter in phases starting in 2020 and extended coverage in subsequent years. The current renewal maintains the system through March 2027 under terms city officials described at the hearing.
Council members pressing for fiscal caution questioned committing another $2.1 million without clearer, independent performance data or the opportunity to renegotiate price terms. Tate said he had been told renegotiation was not available, which influenced his vote against the amendment.
Speakers also raised questions about who can access raw audio or alert logs, how long data will be retained, and whether independent reviews have validated the system’s accuracy in Detroit neighborhoods. Those concerns shaped public testimony and council discussion.
Next steps and oversight
With the contract renewed, several council members and community groups said they will push for clearer monitoring, transparency on data access and periodic audits. The renewal and council remarks signaled interest in oversight but did not set a specific independent audit schedule in the meeting record.
Outstanding questions include which agencies or officials can request recordings or alert logs, the retention period for stored data, and metrics the city will use to measure false alerts versus verified incidents. Council members indicated they expect follow-up reports and may seek additional reviews tied to the expenditure.
