CHICAGO (AP) — The trial of three Chicago police officers charged with lying to protect a fellow officer from criminal prosecution after he fatally shot black teenager Laquan McDonald began with prosecutors pointing to reports they contend were falsified and defense attorneys putting much of the blame on the teen himself. Ex-Officer Joseph Walsh, former Detective David March and Officer Thomas Gaffney “violated the public trust” when they “began to fashion a story (and) create lies that were designed to help (Jason) Van Dyke avoid the consequences of his actions,” Special Prosecutor Patricia Brown Holmes said during opening statements Tuesday.
