But he hadn't gotten away. As he was running away, Officer Wilson fired four shots at (or near) him, while yelling STOP.
At that point, Brown stopped and turned back towards the Officer. He then taunted the Officer (according to early witnesses) with "Whatcha gonna do, shoot me ?" (this is where he had his hands out with palms up). Then, Dorian Johnson (who was hiding behind a parked vehicle) yelled "GO MIKE, GO" (before, or as) Mike Brown charged forward towards Officer Wilson.
Forget the eyewitnesses. Forget the protesters. Forget all the people on both sides of the issue blindly supporting one man or the other. The ony thing that matters is the physical evidence, and that's coming out in drips and drops. So we now know what has long been alleged; there was a struggle for the gun and shots were fired in the vehicle. We now know for the first time that the evidence shows that Brown was wounded in the struggle. We don't know what happened after that, and probably won't until the results of the autopsy are released. Until then I'm still questioning why Bronw would run into the gunfire.
