This is not how I remember the micheal brown shooting. From wiki

147. Which shots?

Actually the forensic pathologist testified (page 198 grand jury transcript) that he could not determine the position of the hands at the time the wounds to his arms were received. More importantly he testified that the only thing he could say about the wounds to the torso were that Brown was facing Wilson as those wounds were sustained. Even if we assume that the fact that the wounds to his arms were to what we normally consider the "front" that his hands were down (which the pathologist declined to do), the wounds to his torso and the non-fatal wound to his head could have been inflicted with his hands up.

Under the best case scenario for cop defenders, the autopsy shows nothing more than that SOME of the shots may have been fired when his hands were down.
