Groups voice concerns about Chicago’s ShotSpotter gunshot detection system – FOX32 (Chicago)

The groups say a study of Chicago police data found that over a nearly 22-month period ending in mid-April, almost 90% of ShotSpotter alerts didn’t result in officers reporting evidence of shots fired or of any gun crime. "These deployments create an extremely dangerous situation for residents, prompting unnecessary and hostile police encounters, and creating the conditions for abusive police tactics that have plagued Chicago for decades."
