I said it may not have happened, if you read the next sentence or 2 you would have seen why I said that may not have happened. you know you have good odds of if you punch someone in the face of injuring your hand right? I'm not saying he did or didn't, but we don't know if he didn't shoot Brown from behind either. WE make an assumption based on what we perceive the facts to be.
How would the officer have a fractured orbital bone if not punched?
