He’s just ignorant, probably an avid MSNBC watcher.
The strong arm robbery isn’t, couldnt possibly be, a justification for killing Brown. Wilson had no knowlege of it at the time the confrontation took place.
The justification are the assault on Wilson and the attempt to take his weapon, followed by Brown turning and charging Wilson, crossing 25 yards before he fell.
Thats it. Any talk about the strong arm robbery by the Left is just a red herring.
My understanding is that Wilson testified he was aware that these guys met the description of the robbers when he confronted them.
The police chief statement to the contrary a couple months ago was apparently mistaken.
