Ferguson police officer Darren Wilson sat down with ABC News and spoke publicly for the first time since fatally shooting unarmed teenager Michael Brown.

UPDATE: Full interview has been posted above.

Yesterday (11/24) a grand jury refused an indictment for Wilson in the shooting death of Michael Brown. Since the announcement, all evidence and documents presented to the grand jury have been released to the public.

The incident with Michael Brown was the first time Wilson had ever used his gun. When asked by the ABC reporter if this incident would haunt him for the rest of his life, Wilson replied that he has a "clean conscience."

Wilson also insisted there was "no way" Brown put his hands up before he fired his weapon—a gesture that has been described by some witnesses. Wilson also added that if he had to do it all over again, he wouldn't do anything differently.

Edited segments of the interview will air on "World News Tonight" and "Nightline" Tuesday evening, and on Wednesday's "Good Morning America."

Full interview will be posted tomorrow, (11/26) so check back for updates to this post.
