The real salient questions are:
1. Was officer Wilson attacked through the car window. The medical reports for him will help here.
2. Was Brown acting aggressively after turning towards the officer. This is going to be harder to establish one way or the other, I think.
Officer Wilson used deadly force.
The question that matters is: was he justified in doing so?
The fact people answer this question based on their worldview is wrong. The question must be answered on the facts.
The Crowd is not the sum of its parts.
