Darren Wilson says he has a clear conscience and wouldn't have done anything differently during his fatal encounter with unarmed teenager Michael Brown. Tonight, the Ferguson, Mo., police officer is speaking publicly about the violent encounter for the first time in an ABC News interview with George Stephanopoulos. Wilson tells Stephanopoulos that he didn't execute Brown, that Brown grabbed his gun in the police car, and that Brown later rushed him so aggressively that Wilson had no choice but to open fire. Wilson also says he has a clear conscience. (See Wilson speak on World News Tonight at 6:30pm EST).
Meanwhile, Ferguson Mayor James Knowles tells reporters that Wilson has not resigned from the Ferguson police force, CNN reports. "No decision has been made," says Knowles. "His current employment status has not changed." Wilson is on administrative leave until an internal investigation is complete. (Sources have said he may step down.) Knowles also criticized a delay in sending National Guard troops to Ferguson, where riots broke out last night and one man died after a grand jury decided not to charge Wilson in Brown's death. "Clearly last night they were needed, much earlier than what time they were deployed," he says. Missouri Gov. Jay Nixon later announced that more National Guard troops would be going to Ferguson due to last night's "unacceptable" violence, NBC News reports. (Read more police brutality stories.)
