The first set of shots equaled to 6. The second set equaled to 5.
What this tells me is that Brown was indeed moving forward. My reasoning for this is simple for anyone with any understanding of shooting a gun. It is much easier to hit a target that is not moving than it is to hit a target that is moving. Since Brown was only hit 6 times according to the coroner that means that the officer was shooting at a moving target. Even assuming that Brown was the claimed 30ft away my 9 year old son could have hit him at least 10 out of the 11 shots fired if he was standing still. I would expect even a half assed trained adult could have hit all 11 times if the target was not moving. So the only logical conclusion is that Brown was indeed moving towards the cop.
There is of course one other explanation, but quite frankly it borders on conspiracy theory and I hate those, besides it wouldn't hold up either.
PS EDIT: I've got a feeling that that "friend" that the person was chatting with was either A: more than just a friend or B: (more likely) That "friend" wasn't really a friend but one of those porn cam girls.
