OP, what is the point you’re trying to make? Based on the few seconds of the actual shooting I would say that it was not justified since the police officer could have backed off and let the kid go on a high speed chase. He also could’ve shot out his tires. However, on the other side, in the moment maybe the cop thought he was about to get run over.
In any case, the video is 5 years old and since you posted the video, what was the outcome of the investigation?
I will add the obvious, an unjustified shooting of a white man does not mean any less and at the same time cannot be equated to the death of a black man at the hands of the police within the context that each death occurs.
