Whoa there: six shots that hit him from the front. Or are we to assume that the officer was such a crack shot that he hit the exact intended target with every shot? Explain again why no disabling shot to the leg by such a skilled marksman.
So the cops have seeker bullets that when they miss turn around and hit the target from the other direction???
Since the cop isn't firing torpedoes we can conclude that the shots came from the direction they hit him. He was facing the cop when he was shot.
We have a bunch of witnesses that say he was running away--since that's not consistent with the facts they're useless. We have a couple that say he charged the cop when challenged--and supposedly one has video showing this. (I have not seen the supposed video.)
Conclusion: He was charging the cop. The altercation in the car that caused a round to be fired certainly shows him a threat. Justified shoot.
