As you know, my theory does not require shots fired while Brown was still fleeing. That may have happened, especially if such shots missed, but we just don't know.
But then you provide a theory, while oddly denying that you are doing so. Your stated theory is that, after being shot by Wilson near his police car, Brown ran from Wilson, Wilson chased him with his gun, and Brown then "turned to resume the assault" and was "charging the officer." Thus, your theory is that, after running from the shooter, Brown changed his mind and decided to run toward the shooter, thereby making it easier for the shooter to shoot him some more.
Seriously, that makes sense to you?
