"Well the story makes me angry and that's why I'm taking time out of my vacation to be with you guys," O'Reilly explained. "I want the 'Factor' audience and everybody else it know that this is just bull, just bull."
O'Reilly complained that the media and some of the public have reached a forgone conclusion about the police killing of black, unarmed teenager Michael Brown, particularly in light of new revelations.
"Most people are upset and certainly they have a right to be upset and make a point that they don't want unarmed people shot for no reason — but there may have been a reason," he said. "There may have been a reason."
O'Reilly said the video released by police on Friday purporting to show Brown stealing cigarettes at a convenience store.
"Now we know he is not a regular guy," O'Reilly said. "We see it on tape. We saw what he did in that convenience store. He’s not a regular guy.”
The Fox host went on to dismiss concerns that releasing details of the robbery constituted a "smear" since the police have stated the officer who killed Brown had no knowledge Brown was a suspect in a robbery.
"There comes a point where, we know what you're up to, alright? We know the racial agitators, we've seen them over and over again," O'Reilly said.
