My money would be on it being the scene forensics.
Bodies that are struck, by multiple rounds, on the upper portion tend not to fall face down, heads toward the shooter, if theyre not moving towards the shooter.
Thats how Browns body was found, as can be seen in the photos of him lying dead in the street, with the blood running downhill towards where Ofcr Wilson was.
It seems like basic physics to me. Browns body may have been twisted around various ways by the impacts, but the positioning of his body is an indication that he was moving forward, with some momentum, when he fell. IOW charging at Wilson.
Yes - the forensics is a big deal. Brown's blood on the gun and in the squad car sure puts the “shot in the back from 20 feet” to rest.
Several black witnesses agreeing with the cop's statement.
Forensics showing he was not shot in the back, or with his hands up - contradicting his friend's statements.
OTOH - they say Wilson told Brown to get out of the street. While that is obviously a reasonable thing to do, I wonder how much testosterone was flowing. By Brown, perhaps walking slowly in the street, and intentionally being rude as the cop car was driving. And how intense Wilson's reaction to Brown was.
Looking at that video of the robbery, it looked like Brown had a real cocky attitude - perhaps because of his large size. And Wilson, having a badge, may also have had a cocky attitude - as perhaps witnessed by the video tape that surfaced of him confronting the guy with the camera awhile ago.
Based on the evidence it seems clear that this was a case of self-defense. But - I wonder how things would have gone differently if both had been a little more polite if my wild assumptions are correct?
The Treehouse did an analysis based on spent casing and Martin's body position,
indicating he was moving forward while Wilson was moving backwards...
