The Chicago City Council has voted 33-14 to retain the controversial ShotSpotter gunshot detection technology, defying Mayor Brandon Johnson's plans to terminate its use. The mayor, who has been critical of ShotSpotter, citing its ineffectiveness and high cost, immediately announced his intention to veto the ordinance. Proponents in the council argue that the technology is a vital tool for police in addressing gun violence, while studies, including one from the city's Inspector General, have questioned its efficacy. Johnson's administration argues that the measure violates the Separation of Powers Act, setting the stage for a potential legal battle. The council's decision reflects a growing divide between the mayor and certain council members regarding public safety strategies, with some aldermen urging a collaborative approach to find effective solutions. The future of ShotSpotter remains uncertain as the mayor's veto looms.
