Activists gathered near the Englewood police district Thursday to decry the city’s decision to extend its contract with ShotSpotter, the company behind an acoustic gunshot detection system that has recently come under heavy fire for allegedly being inaccurate.
The city’s three-year, $33 million contract with the Silicon Valley-based startup was initially supposed to expire Thursday. But Cathy Kwiatkowski, a spokeswoman for the city’s Department of Procurement Services, said the deal was extended for two additional years at the request of the Chicago Police Department, which uses the software to respond to alerts of gunfire.
Tynetta Hill-Muhammad, of BYP100 and Defund CPD, claimed to reporters the contract was stretched out “under the cover of night,” without any public comment or notification to members of City Council. The few dozen demonstrators ultimately called on the city to immediately end the contract and instead invest in communities the technology has been used to monitor, like Englewood.
“We know that the solution is not policing. It is not hyper-surveillance,” Hill-Muhammad said. “We are here because we know that the solution is an investment in life-affirming institutions and resources that will reduce instances of violence and allow people to pursue the fullness of life.”
The demonstration came just hours after the Associated Press published an investigation raising serious alarms about ShotSpotter’s technology, the latest in a series of news reports and studies that have challenged its accuracy and efficacy.
Though its system is closely guarded as a trade secret, ShotSpotter has claimed it’s 97% accurate. The AP investigation, however, found the system could miss gunshots or wrongly detect other sounds as gunfire, and it concluded there were serious issues with using the technology as evidence.
As with another report published in July by Vice, the AP investigation noted that ShotSpotter employees have altered both the location of an alert and the number of gunshots detected. The AP also reported that dispatchers and police officials have previously been able to make some of those alterations.
A company spokeswoman didn’t immediately respond to a request for comment. But a police spokesman stood firmly behind the software.
“In order to reduce gun violence, knowing where it occurs is crucial,” spokesman Tom Ahern said in a statement. “ShotSpotter has detected hundreds of shootings that would have otherwise gone unreported. ShotSpotter is among a host of tools used by the Chicago Police Department to keep the public safe and ultimately save lives.”
The CPD’s use of ShotSpotter came under increased scrutiny following the death of 13-year-old Adam Toledo, who was shot and killed in March by a Chicago police officer responding to an alert from the system. Toledo’s hands were empty when the fatal shot was fired, though he was seen on the officer’s body-worn camera holding a pistol a moment earlier.
After referencing Toledo’s killing — and a study published in May by the MacArthur Justice Center that found 86% of ShotSpotter alerts in Chicago prompted no formal reports of any crime — activist Adwoa Agyepong insisted “no surveillance technology should be used to terrorize the South and West side.”
“Using untested, unverified technology to send police to our communities — that’s horrific,” Agyepong said.
