Dozens of Chicago students gathered outside the Board of Education president's house in the summer of 2020 calling on the school board to end its contract with the Chicago Police Department that day. In a close and controversial vote, the board opted to keep police in schools. Four years later, some of those same kids have since graduated from Chicago Public Schools but were back at the district's downtown headquarters celebrating what they viewed as a mission accomplished. The Board of Education voted Thursday to remove dozens of uniformed police officers from 39 high schools that still have them and, in a separate vote, to drop janitorial giant Aramark as the district's cleaning provider.
