Officer responding to a call on a robbery involving force. Sees a subject matching he description and pulls alongside. Subject pushes the cop back into the car and i the process reaches for he cops gun which discharges. Subject begins fleeing and is shot. You have a suspicion of physical violence against the shopkeeper and a cop assaulted for merely trying to get out of his vehicle. You had the discharge of the weapon, defense will likely say by brown. Not sure if you can prove who actually fired the gun.
To me everything will depend on the distances and trajectories of the shots as well as the tox report particularly now that he primary witness was at least at the robbery and appears to have made conflicting statements to the press regarding his interactions with the decedant. Tox report if he was on pcp or something like that. I can see the cop walking if everything happened very fast and in Close proximity,, but if it was 30 feet away, in the back, hands up I think the officer has some problems.even then, if you have a guy who is running away after attempting to kill a police officer, you might find a sympathetic juror and get a lesser charge.
The robbery accusation was one of the first things I can recall hearing about this, I recalled it being candy however. The delay was clearly timed to coincide with the name, but it was going to come out anyway.
I could see the state ag prosecuting this case, frankly though I'm unsure of the power dynamics there. The locals including he county have demonstrated a lack of actually wanting to seek justice, whatever that may be, in this case and do not appear to be objective, IMHO of course.
