Shotspotter, an acoustic gunshot-detection technology company, has built a network of thousands of sensors across twelve of Chicagoâs twenty-two police districts. The devices detect loud noises that a computer algorithm and human analysts review to determine if theyâre gunshots, and dispatch police to scenes of shootings. The technology is controversial: studies have raised questions about its efficacy and how it impacts police responses, and activists have called on the city to cancel its contract with ShotSpotter for years.
This months-long investigation, which was published shortly before Mayor Brandon Johnsonâs public announcement of whether he will keep his campaign promise and cancel ShotSpotterâs contract. The investigation combined internal company emails, documents obtained from the police department and Mayorâs Office via public-records requests, and analyses of public data.
We found that CPD reported hundreds of missed shootings to ShotSpotter in 2023; that a public safety director complained to the company about a fifty-five-round shooting in 2022 because of broken sensors; executivesâ internal discussions about staffing issues that impacted their ability to repair sensors in Chicago; that the company was warned about electrical code violations on its installations; and that executives lobbied Johnsonâs administration to keep the contract.
ShotSpotter Lobbied Mayorâs Office ahead of Budget Vote
After Johnson was elected in April 2023, ShotSpotter CEO Ralph Clark issued a public statement congratulating the mayor-elect. That same day, Clark sent an email to employees that blamed the companyâs share price drop on Johnsonâs victory and said executives planned to lobby support for renewing the contract. Emails obtained from the Mayorâs Office reveal how that lobbying effort played outâand show executives met with mayoral advisor Jason Lee days before the 2024 budget vote in City Council.
CPD Reported Hundreds of Missed Shootings to ShotSpotter
In December 2022, two men were wounded in a hail of bullets as they waited for food in a gyro shop in Back of the Yards. The next day, a Public Safety Administration director complained to a ShotSpotter executive that the companyâs senors failed to detect the shooting. Data we obtained from CPD shows the department reported hundreds of misses to ShotSpotter in 2023. Internal emails show executives blamed the miss on three downed sensors in the vicinity, but didnât know when the company would be able to repair them. Other emails show ShotSpotter managers were repeatedly warned that sensor installations were violating Chicagoâs electrical code.
CEO Says Johnsonâs 2024 Budget Includes ShotSpotter
In November, the day before the City Council voted on Mayor Johnsonâs 2024 budget, ShotSpotterâs CEO told investors in an earnings call that there was a line item in the budget for acoustic gunshot surveillance technology. Both the CEO and a spokesperson for the mayor denied anyone had given the company the contract would be extended.
