Chicago plans to end use of controversial gunshot detection technology

Mayor Brandon Johnson's office announced that Chicago will not renew its ShotSpotter contract and intends to discontinue the use of the controversial gunshot detection system by the end of this year. The decision comes after concerns over the system's accuracy, racial bias, and potential misuse by law enforcement.
Controversy surrounding shotSpotter
The ShotSpotter system, which utilizes an artificial intelligence algorithm and a network of microphones to identify gunshots, has faced criticism in various cities, including Chicago. An investigation by the Associated Press highlighted a case in which a Chicago man was incarcerated based on scant ShotSpotter-generated evidence, only to be released later due to insufficient evidence.
With the city's $49 million contract with SoundThinking, a public safety technology company, set to expire on Friday, Chicago plans to phase out the use of ShotSpotter technology by late September, as per city officials.
Focus on alternative strategies
In a statement, the city expressed its intention to allocate resources towards strategies and tactics that have proven effective in reducing violent crime. The decision-making process will involve consultations with the community, violence prevention organizations, and law enforcement, aiming to create a safer Chicago for all.
Community consultation and future plans
During the interim period, both law enforcement and community safety groups will assess tools and programs aimed at enhancing both safety and trust, and subsequently issue recommendations. The announcement did not elicit an immediate comment from a representative of SoundThinking.
Mayor's stance and police response
Mayor Johnson, who campaigned on a pledge to end the use of ShotSpotter, has been at odds with police leaders who have lauded the system. The police argue that crime rates, rather than residents' race, dictate the deployment of the technology.
While violent crime, including homicides and shootings, has decreased nationwide to levels similar to those before the COVID-19 pandemic, property crimes have seen an increase in certain areas. In Chicago, the downward trend in violent crime has persisted into 2024, with a 30% decrease in homicides reported at the start of the year.
The Chicago Police declined to comment, referring inquiries to the mayor's office. Community public safety groups have contended that the system leads to unnecessary and confrontational police interventions in predominantly Black and Latino neighborhoods. Concerns regarding accuracy, such as instances where the technology incorrectly identified fireworks or motorcycle sounds as gunshots, have prompted cities like Charlotte, North Carolina, and San Antonio, Texas, to terminate their ShotSpotter contracts.
While the Stop ShotSpotter Coalition lauded the announcement, they urged Chicago to discontinue the use of the technology sooner, advocating for more substantial support and solutions for victims, survivors, and communities most affected by gun violence.
