WASHINGTON — Ferguson Police Officer Darren Wilson says he “never wanted to take anybody’s life” and feels sorry about the death of Michael Brown.

But Wilson sais in an interview with ABC’s “Good Morning America” that aired this morning that he followed his training when he shot the unarmed black teenager.

During their confrontation, he says, “The only emotion I ever felt was fear and then it was survival and training.”

Wilson says he only fired at Brown when Brown was facing him, and never when his back was turned. And he says he saw in the teenager a high level of aggression and anger that was “almost unfathomable.”

Wilson says he understands Wilson’s parents’ anger because they are grieving their son. He says, “I’m sorry that their son lost his life.”

Also this morning, Brown’s mother says it has been a “sleepless, very hard, heartbreaking and unbelievable” time for her since the announcement that a grand jury didn’t indict Wilson for killing her son.

Lesley McSpadden said during an interview on NBC’s “Today” show today that she also felt that Wilson’s description of her son as looking demonic during their Aug. 9 confrontation was disrespectful and “added insult to injury.”
