>> This police dash cam footage showing a Chicago cop shooting dead 17-year-old Laquan McDonald in 2014 directly contradicts officers statements of the incident. And on Tuesday three cops were indicted on charges of trying to cover up the killing. McDonald was holding a knife and walking in the middle of the street when he was confronted by multiple police officers.
Officer Jason Van Dyke fired 16 shoots killing the black teenager. Van Dyke's partner and two other cops initially said McDonald lunged at Van Dyke in an aggressive manner. But the video showed Macdonald was walking away from police when Van Dyke killed him.>> You are liers. My conscience has been truly.
>> The shooting sparking protests and a federal investigation into the conduct of the Chicago Police Department. Van Dyke was charged with first degree murder the same day the footage was released in November 2015. The special prosecutor investigating the killing saying the indictment unsealed Tuesday, quote, makes clear that these defendants did more than merely obey an unofficial code of silence.
Rather, it alleges that they lied about what occurred to prevent independent criminal investigators from learning the truth. Lawyers for the officers could not be reached for comment. The three cops are set to be arraigned July 10th.
