You are so ignorant I don't even know why I am wasting my time replying to you, but for the benefit of people with brains who actually want to consider this case, I will.
Police officers are not trained to try and shoot at people's arms, whether their arms are at their sides or up in the air. It makes no sense if he had his arms in the air that the cop would aim at his arms. If they have to shoot, they aim at center mass. If the target is moving, there is no telling where those rounds are going to end up. By FAR, the most plausible scenario here is that the first 4 shots, aimed at center mass, by a police officer who had just had his eye socket smashed and was under extreme stress, randomly hit in the same general area of the right arm and chest. As the target got closer and was obviously not being stopped by center mass shots, head shots (we have no idea how many) were attempted, and two of them hit. This all happened in a matter of a couple of seconds by the way, the cop did not have time to square up and try to line up his shots perfectly.
I am certainly not a ballistics expert but even my extremely limited knowledge tells me my scenario is about 1000 times more likely than yours is.
