Alds. David Moore (17th), Stephanie Coleman (16th), Peter Chico (10th) and other aldermen are joining a handful of business leaders, clergy, and others to urge Mayor Brandon Johnson to reactivate ShotSpotter, which uses acoustic sensors throughout the city to pick up the sound of gunfire to dispatch officers to the location of shootings.

Chicago leaders are seeking to reinstate the deactivated ShotSpotter system to improve public safety and response times.
