FILE - In this Nov. 24, 2015, file photo, Chicago police officers line up outside the District 1 central headquarters in Chicago, during a protest for the fatal police shooting of 17-year-old Laquan McDonald. Special prosecutor Patricia Brown-Holmes announced Tuesday, June 27, 2017, that three Chicago police officers were indicted on felony charges that they conspired to cover up the actions of Chicago Police Officer Jason Van Dyke in the killing of McDonald. The indictment, approved by a Cook County grand jury, alleges that one current and two former officers lied about the events of Oct. 20, 2014 when Van Dyke shot the black teenager 16 times.
