The "dozen witnesses" corroborating the Wilson's side of things was pretty widely debunked since it was based off of some unreliable/faked information.
Besides, Wilson and the whole Ferguson PD never even filed a damn Incident Report about the shooting. Damn near the whole police department have been lying about the murder.
Exactly, and the police department never revealed a "public statement" about the incident from Wilson at all so I don't understand why people keep bringing up a statement that doesn't exist. The PD only loosely passed along his supposed justification for shooting. They didn't file an incident report because they passed the case off to county and county supposedly has one, but aren't going to release it until the Grand Jury they have supposedly looking over the evidence makes a decision whether to pursue charges on the officer or not.
Wilson hasn't said anything at all because he's in hiding and probably wouldn't be allowed to say much of anything anyway. That "Josey" person is an anonymous person claiming to be a "friend." Unlike the rest of the witnesses who have come forward publicly, nobody has any valid proof that that person is who they say they are and to top it off, they weren't even there, so anything they are saying is relayed from an obviously bias source (supposedly Wilson himself, but only after the story is filtered through his "significant other" and THEN passed along to "josey") if at all true, which isn't likely at this point.
