No it's only relevant to the visuals I have been trying to create. Like I said, it's not a case cracking question.
Fitting the evidence to the eye-witness accounts:
There's a struggle at the car, the gun goes off, hits Brown in the palm and reenters his chest. The wound is not life threatening.
Brown panics and runs.
Wilson gets out and starts shooting at Brown (the volley of 6).
One round hits Wilson (the arm graze) (only seconds are going by here).
And either the arm hit, the fact Wilson is shooting or both, Brown gets a grip on his panic and turns around to surrender. Within this action, Wilson shooting 6 rounds, Brown getting hit in the arm, Brown stopping and turning around, it all takes place during the volley of 6 shots.
Wilson pauses for 3 seconds.
Now either because his anger is still boiling/unspent, or because he negligently perceives Brown's attempt to surrender as coming toward him, Wilson fires four more rounds.
But during that 3 seconds Wilson wasn't shooting, Brown has to have at least gotten down, started to get down, fell down or completely doubled over (which explains both Brady's and Mitchell's accounts) in order to explain the trajectory of the fatal head shot that then dropped Brown causing the facial injuries Baden described.
In either case, unspent anger or negligently not recognizing Brown was not attacking, Wilson used excessive force killing Brown unnecessarily.
That Wilson seems to have made up the claim Brown was charging at him (if we are getting accurate accounts of Wilson's story) because the physical evidence simply does not bear that claim out, and especially if he made up the claim Brown taunted him which definitely doesn't fit the physical evidence, then that suggests to me that Wilson knows full well he shot those last 4 shots in anger.
That last part is just my speculative opinion. We don't really know what Wilson's actual story is. I accept that he might have negligently shot because he imagined Brown coming at him.
I don't accept that there is any evidence Brown was charging or threatening Wilson. You have to suspend critical thinking and accept the racist stereotype of black men and the racist stereotype that all the black witnesses are conspiring against Wilson to think that was the case.
