In my opinion, the current situation involves four key narratives, two of which are specific to the incident, two of which are generalizations based on it. There are others, but to me these are the main ones, and what happens is people mix and match these to suit their own purposes:
1) The officer was mad at Brown and shot him in anger, rather than self-defense or as a lawful effort to apprehend him.
2) The officer was justified in firing because Brown had attacked him, and it reasonably would have appeared he was about to do it again.
3) The incident is emblematic of the mistreatment of the black community, via profiling and excessive use of force, by the police, which are predominantly white.
4) The incident is emblematic of the failure of the black community on the whole to come to grips with the criminality within their own community and particularly the youth.
Everyone is picking and choosing facts, statements, and actions in the other community that buttresses their already long-held views and resentments. We are getting nowhere, and will get nowhere until both sides sit down and admit that the other has a point.
