The City Council Wednesday could again rebuke Mayor Brandon Johnson’s plan to rid Chicago of ShotSpotter, just days before the gunshot detection technology is set to go offline. Aldermen are set to vote on a long-shot ordinance some say would compel police Superintendent Larry Snelling to continue using the tool.

"The mayor referenced the veto because the thing that passed is in violation of the Separation of Powers Act," Chicago Corporation Counsel Mary Richardson-Lowry said at the same press conference. "The legislative branch cannot compel the executive branch to act, hence the item is a vetoable item and the mayor is going to exercise that privilege."
