So you think it is possible that Michael Brown was backpedaling his fat ### away from the cop like a corner back, hence no bullet wounds in the back?
Based on what I've read of Wilson's account of the event and witness interviews, my most likely version of events is that there was an altercation at the car due to the aggressive nature of both parties (Wilson yelled an order, Brown yelled back, Wilson backed up to confront, some kind of fighting took place at the car window). Wilson pulls his gun and aims it at Brown, threatening to shoot him. Brown tries to deflect the gun barrel away from his body and receives the wound to the inside base of his right thumb and begins to run away (he passed two parked cars or roughly 30 feet, per Wilson's interview on Aug 10) before stopping and turning toward Wilson. Here's where I think the key mistake happens. Wilson claims that after Brown turned, he was "wild eyed" and "hopped" as if he were going to start running and reached his right arm down toward his waistband. Wilson emphasizes this point about him reaching down several times. It was during this "first stride" that Wilson began firing (and, per his testimony, Brown channeled The Terminator). Per Wilson, Brown covered about 10-15 feet before falling to the ground dead, charging all the way by his account.
What I think is more plausible than the classic "superhuman black man" trope that Wilson is alleging was that Brown turned back when he realized he had been shot in the hand (with an exit wound going down through a bit of his forearm, a nasty wound and bad enough to cover Wilson's hands in Brown's blood) and brought his injured arm down to his waist (how many of us have hurt our hands and instinctively dropped your hand down toward your waist?), maybe even stumbling forward to produce the "hop" motion Wilson says he saw. Wilson, fresh off of fighting with this man, interpreted the motion as a move for a weapon and unloaded. Brown is only alleged to have covered 10-15 feet before falling dead. Since this is FBG's, I assume most of you have stepped onto a football field before and have some sense of what 3-5 yards looks like on the ground. I seems very plausible for a 6'4" person to stumble forward and cover 3-5 yards in total.
That falls much more closely in line with the majority of witness accounts, which indicate the Brown turned back toward Wilson, moved a short distance toward him before he died, and did not have his arms raised above his head (several said his arms were at his sides, several say that he raised them to chest level). Draw your right hand toward your body as if it has been injured and put your left arm out in front of you as if you're protecting yourself. To me, that's a normal stance that reflects the injury known to have happened to Brown, and which would result in the conflicting testimony of witnesses, none of which saw the entire event and all of whom saw it from different angles.
