The Detroit City Council has voted to renew its agreement with SoundThinking for the ShotSpotter gunshot detection system, a decision that will keep the crime-fighting technology operational in the city through March 2027.
The measure passed by a narrow 5-4 margin following a Tuesday hearing where several councilmembers and community critics voiced concerns about the system's high cost and potential privacy implications.
ShotSpotter utilizes acoustic sensors, typically mounted above city streets, to identify sounds resembling gunfire. When a suspected shot is detected, the system automatically alerts law enforcement personnel.
Contract Renewal Sparks Heated Debate
Council President James Tate, who has previously supported ShotSpotter's presence in Detroit, ultimately opposed the renewal. His primary objection centered on the $2.1 million price tag, which he found difficult to justify.
I have a challenge with that dollar amount. It’s not about the technology. When asked, would they renegotiate the contract, the answer was no, because we’ve been giving you a deal in the first place, so that leads me now to a situation where I cannot support this particular amendment.
Councilmember Gabriela Santiago-Romero also voted against the extension, citing insufficient evidence of the technology's effectiveness and a lack of public support. She expressed reservations about whether the system truly benefited the community given its expense.
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.
Concerns Over Privacy and False Alerts
Gabrielle Dresner, a policy strategist with the ACLU of Michigan, testified against the contract extension, raising alarms about potential negative consequences. Dresner argued that false alerts generated by ShotSpotter could lead to unnecessary police deployments, potentially reinforcing negative stereotypes about minority communities.
Critics further questioned whether the use of acoustic microphones to monitor public spaces constituted a form of surveillance. They also sought clarity on who would have access to any audio data collected by the system.
Documented Successes Cited
Despite the criticisms, proponents of ShotSpotter pointed to instances where the technology has proven successful. Assistant Chief Franklin Hayes recounted a case on Detroit’s west side where a ShotSpotter alert led officers to a gunshot victim who was found alive, even though no one had placed a 911 call.
A History of Controversy
The ShotSpotter technology has been a source of public debate in Detroit since the city first entered into a contract covering specific police precincts in 2020. The system faced similar controversy during its previous renewal discussions in late 2022, underscoring the ongoing divisions surrounding its implementation.
