On Monday, the City Council Committee on Police & Fire advanced an ordinance that would place the decision to keep ShotSpotter at the ward level, with individual alderpersons choosing whether or not to retain the controversial gunshot-detection technology. The legislation, sponsored by 17th Ward alderperson David Moore, openly defies Mayor Brandon Johnson, who fulfilled a campaign promise by announcing in February that he would end the cityâs contract with ShotSpotter in September.
The ordinance would also require the Chicago Police Department (CPD) to collect data on ShotSpotterâs accuracy; how often ShotSpotter alerts have no corresponding 911 calls; response times to alerts and 911 calls; and how many shell casings, weapons, and arrests resulted from an alert. The department would be required to post its findings online and produce monthly reports for the City Council to review.
To find out which wards would be affected by canceling ShotSpotterâs contract, the Weekly mapped the locations of ShotSpotter sensors in Chicago. The locations were secret until they were revealed in leaked company documents and first published by WIRED in February. According to the data, which is from 2023, ShotSpotter has sensors in thirty-five of the cityâs fifty wards.
With 184 sensors, the 10th Ward has more than any other ward. But the 10th is also the cityâs largest ward, at roughly six-and-a-half square miles. The 8th Ward, which is a little more than half the size of the 10th, has 152 ShotSpotter sensors, the most per square mile. The 19th Ward has the fewest among the wards that do have them: in the 19thâs northeast corner, there is a single sensor atop a utility pole in an alley at 87th and Winchester.
Itâs unclear how the city would transition from ShotSpotterâs current contract to ward-level agreements if the ordinance passes the full City Council. The current contract, which was initially signed in 2018 and extended several times, requires ShotSpotter to monitor twelve police districts on the South and West Sides. In February, the Weekly revealed that ShotSpotter additionally monitors areas around billboards along the Kennedy Expressway on the Northwest Side for free.
While some wards are wholly contained within a single district, many ward and district boundaries overlap. Several wards cross boundaries with three police districts: the 21st Ward on the South Side, for example, overlaps with the 5th (Calumet), 6th (Gresham), and 22nd (Morgan Park) districts.
In Mondayâs committee meeting, Moore said he sponsored the ordinance placing the decision with the wards because he felt Johnson âunilaterally made a decision to end ShotSpotterâ despite the fact that CPD superintendent Larry Snelling and others support keeping it. There are about seventy-five ShotSpotter sensors in Mooreâs 17th Ward.
âWeâve heard from different voices in this,â Moore said. âJust as communities that do not want SoundThinking/ShotSpotter in their wards, other wards should have the ability to decide whether they want to keep the residents safe, as the wards utilizing ShotSpotter versus the ones who do not want to use it.â He suggested the ordinance is primarily designed to prompt CPD to collect more data about the technologyâs accuracy and efficacy.
Ald. Pat Dowell, a mayoral ally whose 3rd Ward has nearly sixty ShotSpotter sensors, spoke in favor of the ordinance. âIâm a supporter of ShotSpotter,â she told the committee. âI believe that it works, and in talking to both patrol, street cops, people in the administration, they are supportive of the technology.â Dowell cited a recent shooting that she said wounded three people in a nonresidential block in her ward, and said a ShotSpotter alert was âthe only way that police respondedâ to that incident.
Ald. Jeanette Taylor, a Democratic Socialist who supported the mayorâs campaign, asked why ShotSpotter representatives and Snelling werenât at the committee meeting, and said her 20th Wardâs experience with the technology has been mixed. There are 109 sensors in the 20th ward, or about 21 per square mile.
âI live in a ward [that] has benefitted, but also, ShotSpotter has been problematic,â Taylor said. She noted that her Washington Park ward office overlooks the Dan Ryan and said she could âcount the number of times on my fingers and toesâ when police have arrived in response to a ShotSpotter alert from a car backfiring on the expressway.
âIf weâre gonna spend money on something, let it be something that actually works, or something that we can collect clear data on,â she said. âI am not interested in throwing money at ShotSpotter just âcause theyâve been there.â She added that without more information, she was not willing to vote for the ordinance.

Missed Shots
Ald. Desmon Yancy, whose 5th Ward abuts Taylorâs and includes parts of Hyde Park, Woodlawn, and South Shore, told the Weekly he was not consulted in the mayorâs decision to cancel the contract, nor was he aware of the mayor involving any other alderpersons who have ShotSpotter in their wards. There are eighty-one ShotSpotter sensors in the 5th Ward.
âWe should be looking at the tools that we have to keep crime at bay,â Yancy said.
The perspectives of residents affected by contract cancellation often get lost in the conversation about ShotSpotter, he said. As part of his most recent 5th Ward newsletter, Yancyâs staff circulated a brief survey that asked residents if they are in favor of or against the technology. Although not finalized yet, the survey results of 5th Ward residents reveal overwhelming support for keeping ShotSpotter, Yancy said.
âPeople are still reticent or reluctant to call the police even when they hear shots,â he added. âTo have a resource like ShotSpotterâeven if it is until thereâs a better resource that comes alongâI think itâs valuable for the community.â
According to Delmarie Cobb, a veteran political consultant and longtime commentator on Chicago politics, this kind of back and forth between City Council and the mayor is how the cityâs democratic institutions are meant to operate.
âItâs not supposed to be a rubber stamp for the mayor,â she told the Weekly.Â
Cobb added that sheâs thankful that long gone are the days when mayors like Richard M. Daley and Rahm Emanuel demanded and won unanimous support for their favored policies from the City Council.
But so too is she grateful that the legislative body isnât reverting to the days of the Council Wars in the 1980s, when a group of reactionary white alders tried to stymie Mayor Harold Washingtonâs progressive agendaâand were successful for much of his first term. Cobb said she sees the discussion about the proposed ordinance as an opportunity for the mayor to be more transparent about his decision-making process.
âWhat weâre seeing is healthy,â she said. âThis is the kind of debate that we should have publicly.â
