What’s the problem with the pause?
After 7 shots, one may be assessing the situation, and/or incredulous at the fact that Brown was still closing distance for attack.
The pause means Brown had a chance to stop after ample warning to. He didn’t.
My understading of the autopsy, from other analyses ive seen of at least what’s been released (the family one, not the two others) are that the entry wounds are consistant with a stitching of the six shots from lower left to upper right with the second to final shot hitting Browns right eye and the final shot impacting the top of the skull as Brown was falling forward. All taken by an officer who was impacted by having taken blows to the face that had degregaded his vision in one eye.
That would mean that the six shots that struck were fired in succession, withou pause. That doesn’t preclude other shots being fired, but does cause problems with the 7 + pause + 4 allegation.
