Paraphrase; fuck clues, look at the reaction. Not the action that lead up to that. Everything but what I want to focus on is irrelevent. A man died because he simply didn't provide a license! He complied and the guy shot him because he was black. End of story.
The guys actions had consequences, he didn't shoot him upon finding out he had no license. He didn't shoot him or seem to care about the bottle of gin claimed to be air freshener. The guy DRIVING OFF while he's trying to detain him is THE REASON he opened fire. In a span of 2 seconds he made a choice to open fire while the guy was trying to take off WITH HIS ARM IN THE VEHICLE!
You're saying the events aren't important yet he was calm and frank with the driver up until he tried to flee. Again WITH HIS ARM in the car putting him in danger.
Did he open fire over the license, the display thing, the gin bottle OR the attemp to flee while being detained? Your logic implies that his actions had no result/outcome of the situation leading to deadly force. That's evidently nonsense.
He was starting his engine to not drive? Put it in drive to park? Yes, a car couldn't and doesn't ever result in injuries when operated recklessly! Great point.
I guess it's much easier to just go with: Holy fuck, hope the cop dies and rots in prison! He opened fire on him the moment he saw he was black!
