The officer, who was told on Monday he would not face charges over the 18-year-old's death, broke his silence in an interview with ABC News.

He said he had a "clean conscience" because "I know I did my job right".
Asked about witness claims that Mr Brown put up his hands, Officer Wilson said: "That would be incorrect. No way."
Describing the August incident, the 28-year-old said: "I take out [my gun] and point it at him and what I said was 'Get back or I'm going to shoot you.'
"Immediately he grabbed the top of my gun. When he grabbed it he said 'You're too much of a p***y to shoot me.'
"While he is doing that I can feel his hand coming over my hand and get inside the trigger guard. He tried to shoot me with my own gun."
Officer Wilson added that Mr Brown was a "powerful man" who "wanted to kill me".
The US Justice Department is conducting a separate investigation into possible civil rights violations that could result in federal charges against Officer Wilson.
