This is just in from the Ferguson PC press conference:
The initial contact between Mr. Brown and the police officer who shot him was NOT related to the robbery at the convenience store.
SO, in actuality, my original statements that the officer did not know Big Mike was a suspect in anything were correct ?
IRONY. If Big Mike and friends had not tried to block the police car, he would likely be alive and might have gotten away with it(the robbery/assault). Or at least not been caught for a few days.
Brown didn't know that at the time. He'd have every reason to believe he was about to be arrested for theft and assault of the store clerk.
