In late May, the City Council voted to take control of the contracting process for the city’s ShotSpotter system from the mayor’s office, effectively keeping the technology in place until at least November, when the contract is set to expire. In 2017, when Chicago began expanding ShotSpotter into about half of the city’s neighborhoods, mostly in Black and Hispanic communities with higher rates of firearm violence, there were very few independent studies on gunshot detection technology in general and none on Chicago’s s system. While the police in both Chicago and Kansas City spent more response time at ShotSpotter locations as opposed to 911 calls, none of this activity led to a reduction in crime.
