The Impact of Removing Gunfire Detection Technology in Chicago
The decision made by Mayor Brandon Johnson to eliminate gunfire detection technology from Chicago streets has led to delayed emergency responses for shooting victims. This move has resulted in instances where victims were left to seek help themselves or wait for an extended period for authorities to locate them.
Mayor Johnson terminated the city’s contract with ShotSpotter in September 2024, against the wishes of a majority of the City Council and CPD Supt. Larry Snelling. Since then, at least 71 shooting victims have experienced longer response times from first responders, with a significant number of them succumbing to their injuries.
Two recent incidents highlight the consequences of this decision. In Bronzeville, two victims were shot, and no 911 calls were made to report the gunfire. A passing patrol car eventually assisted one victim, while the other had to wait over eight minutes for help to arrive.
One victim, an 18-year-old man, arrived at Provident Hospital with a gunshot wound to his thigh, while a second victim, an 18-year-old woman shot in the abdomen, was found by officers. The absence of ShotSpotter technology meant that police had to rely on general area sounds to locate the victims, resulting in delays in response time.
In another incident, a 17-year-old boy who had been shot in the arm and hand had to flag down a CPD patrol car for help. The lack of 911 calls reporting the gunfire meant that the boy had to wait for assistance, with officers applying a tourniquet before he was taken to the hospital.
Aldermen Michelle Harris and Jeanette Taylor, who had differing views on the effectiveness of ShotSpotter, expressed concerns over the removal of the technology. Harris noted the quick response times enabled by ShotSpotter in her ward, while Taylor emphasized the need for reliable and effective tools for law enforcement.
The decision to end the use of ShotSpotter in Chicago has raised questions about public safety and the need for advanced technologies to combat gun violence. The impact of this move on emergency response times and the safety of residents remains a topic of debate among city officials and community members.
As Chicago grapples with the aftermath of removing gunfire detection technology, the discussion continues on how best to ensure the safety and well-being of its residents in the face of ongoing gun violence.
