Cambridge City Ends ShotSpotter Contract Amid Concerns
A Massachusetts city has decided to terminate its contract with ShotSpotter, a gunshot detection system used to identify potential shootings. This move reflects growing concerns about its reliability and possible over-policing effects.
ShotSpotter operates through a network of acoustic sensors placed above streets in various neighborhoods. These sensors detect sounds resembling gunfire and automatically notify law enforcement. Despite its aim to enhance crime-fighting efforts, critics argue the system can misidentify noises and may be linked to federal immigration enforcement efforts.
Recently, the Cambridge City Council voted to end its agreement with the company following a similar decision by Chicago, who announced it would not be renewing its contract with ShotSpotter. According to Boston.com, five council members supported ending the contract, while two voted against, and two abstained. The city’s officials are tasked with discontinuing the system within 90 days, including removing devices throughout Cambridge.
The technology, managed by Soundthinking, claims to save lives, speed up police response, and aid evidence recovery. It sends alerts to police within 60 seconds of detecting a gunshot. During the council meeting, both Cambridge City Manager Yi-An Huang and acting Police Commissioner Pauline Wells highlighted cases where ShotSpotter detected gunfire incidents not reported through 911.
Nonetheless, detractors argue the system lacks solid scientific backing due to false positives and other issues linked to unrelated loud noises. Additionally, there are fears about a connection between Soundthinking’s law enforcement database and Immigration and Customs Enforcement (ICE), which raises concerns in Cambridge over data sharing and resident privacy.
City Councilor Ayah Al-Zubi, a co-sponsor of the resolution to dismantle ShotSpotter, voiced her worries about privacy risks linked with federal ties. She emphasized that while interest existed in the technology years ago, its effectiveness and drawbacks are now better understood.
In response, Soundthinking defended its services in a statement, asserting ShotSpotter’s unbiased nature and reaffirming its commitment to assisting communities in reducing gun violence while respecting privacy.
