From my standpoint, it doesn't matter one bit if Brown was charging at Wilson or walking slowly towards him. Both sides acknowledge and agree that each of the following events happened:
1. There was an altercation between Brown and Wilson in the police car.
2. Brown threw punches at Wilson.
3. Wilson discharged his weapon during the altercation.
4. Brown fled away from the car.
5. Wilson emerged from the car, drew his weapon, and told the suspects to freeze.
6. Brown turned around and was facing Wilson. All the shots were entrance wounds to the front of his body.
7. The crime scene evidence showed that Brown moved towards Wilson between the first shot and the last.
NONE of these facts are in dispute. Why does it matter if Brown was "charging" Wilson or walking slowly towards him? After what had just happened, Wilson had every reason in the world to use deadly force at that point. If he had shot Brown in the back while he was fleeing, there wouldn't be an argument. If he had shot Brown while his hands were up and he wasn't moving, there wouldn't be an argument. If he had shot Brown from 100 feet away, there wouldn't be an argument. But that's not what happened. Brown had just assaulted a cop and was resisting arrest. The cop was obviously in a very dangerous situation, as evidenced by the fact that he had already fired his weapon IN THE CAR! I mean, seriously Tim - do you really think it is reasonable to expect him not to shoot there when Brown doesn't immediately freeze, and then starts walking towards him? After all that occurred? I don't care if he's walking at a snail's pace. If he doesn't stop immediately and comply with all directions, after assaulting a cop, then yes - he deserves to die. Sorry if that offends your delicate sensibilities, but that's the way it is.
Michael Brown robbed a convenience store, bullied an old man, walked defiantly in the middle of the street, then assaulted a cop. I feel bad for his parents, and in some way I also feel bad that his life came to such a horrible end. But let's not make this guy into a martyr or a victim. It was borderline suicide by cop.
