Transcript for Exclusive Interview With Ferguson, Mo., Officer Darren Wilson
speed. Right. Begin with Ferguson. Dozens arrested as the protests got out of control overnight again. And another police car set on fire. I sat down with officer Darren Wilson telling his side of the story. I used my door to push him back and yell at him. He stares at me. And I look back, punches start flying. He threw the first punch? Yes. He threw the first one and hit me in the left side of my face. There was a barrage of swinging and grabbing and pulling for 10 seconds. He was in the car physically, he had ducked his head and come into the vehicle with me. Where is your gun? I keep it on my right hip. I point it at him. I said get back or I'm going to shoot you. And immediately he grabbed the top of my gun and said you're too much of a To shoot me. I could feel his hand trying to come over my hand and get inside the trigger guard and shoot me with my own gun. He got off two shots in the car. I started to -- He started to run? He started to run. Okay, I missed, the round didn't hit him. I go to exit my car. I use my walkie, shots fired, send more cars. And I chies after Michael brown. You describe him as a demon in the car. Do you know where that word came from? What were you seeing at that moment? It was just such a high level of intensity and aggression and anger that it was almost unfathomable to see it. How is this happening. It was shocked. And you're positive that you'd have that exact same reaction if you were white. Yes. Some of the witnesses have said they thought you were out of control. That somehow you had snapped. That would be incorrect. There was never -- the only emotion I ever felt was fear, and then it was survival and training. We know from the autopsy reports that no shots went into Michael brown from the back. Did you fire any shots when he was running away. No. Only fired to his front. Correct. As you know some of the eyewitness's said at the moment he turned around he turned around and put his hands up. That would be uncorrect -- incorrect. No way. No way. Some witnesses have also said they saw you stand over him and shoot him in the top of his head. Would be incorrect. He's down now. Yes. You know he's dead? Yes. They tell you afterwards, there are times you won't remember where it's fast or slow. That was the slow motion for me. And I saw the face he had go blank. Everything was just blank and I knew immediately that he had passed. What did you think? Need help. I got back on the radio and I said, send a supervisor and every car we have. You never shot your gun before, and now a man is dead. Uh-huh. Does that put you in shock? What are you feeling at that point? Shock is a good way to describe it. To the a cop wants to use their gun today. No one wants to. No one ever wants to do that. It happened in a minute. The brown family came out with a statement. We are profoundly disappointed that the killer of our child will not face the consequences of his actions. What do you think when you hear that? I think those are grieving parents mourning the loss of their son. They're saying that you have to face the consequences of your actions. Do you think there's anything you can say to them that can change their minds or hearts? I don't think there's anything I can say. But, again, I'm sorry that their son lost his life. It wasn't the intention of that day. It's what occurred that day. And there's no -- nothing you can say that's going to make a parent feel better. Do you feel any remorse? Everyone feels remorse when a life's lost. Like I told you before, I never wanted to take anybody's life. You know, that's not the good part of the job. That's the bad part of the job. So, yes, there is remorse. George, as you know, a lot of reaction to the interview. And people not only listening closely to what he said, but he he said it. And many people are questioning his demeanor. Yeah. You know, he's very straight forward, very clinical in describing what happened. He has been telling the same story since going back so the police station that afternoon. Not a lot of emotion. He sees himself as a police officer doing his duty that day. And he's not going to give much more than those facts. And in fact he told you he felt he was doing his job. Because of that, he says he has a clean conscious.
