WATCH: Officer Darren Wilson: ‘All I Wanted To Do Was Live’

(FERGUSON, Mo.) — Ferguson police officer Darren Wilson has spoken out to ABC News for the first time publicly since fatally shooting a black teenager, Michael Brown, and he said that he would not do anything differently.

Speaking exclusively to ABC News' George Stephanopoulos, Wilson said that Brown reached into his police car and grabbed for his gun, causing Wilson to fear for his life.

"All I wanted to do was live," said Wilson, whom the grand jury declined to indict in connection with the fatal shooting in August.

He told ABC News about the struggle he faced with Brown as the teen allegedly punched Wilson in the face.

"I didn't know if I'd be able to withstand another hit like that," Wilson said.

"I had reached out my window with my right hand to grab onto his forearm 'cause I was gonna try and move him back and get out of the car to where I'm no longer trapped," Wilson said.

"I just felt the immense power that he had. And then the way I've described it is it was like a 5-year-old holding on to Hulk Hogan. That's just how big this man was," Wilson said.
