I know, right? Like, he had already taken out his aggression on that store clerk. He couldn’t have had any aggression left in him.
The other aspect of this is: "Hey, the officer was unaware of the robbery when he stopped Brown."
Guess what? Brown didn't know the officer was unaware of the robbery.
Brown probably thought the officer already knew about the robbery, and that he was about to go to jail for robbery.
Brown's behavior was likely spurred by his own guilty mind.
If he hadn't done anything wrong, he would likely have taken the stop much less seriously and been less inclined to grapple with the officer.
And Citizen Zed, admitting he had “roughed up” a clerk, managed to omit Brown had stolen an almost $50 box of cigars. Astoundingly,it was not the clerk who called it in to police (too afraid to reprisals to turn him in), it was another customer in the store.
