From what I heard it went like this...
Guy robs store. Runs away, jaywalks.
Cop says "get out of the middle of the street, that is dangerous!"
Guy thinks "OH SHIT HE KNOWS THAT I ROBBED THAT ONE FOO"
Attacks the cop, cop wrestled him down, hand cuffed him, and tossed him in his car.
Guy escaped hand cuffs and went for the cops gun, cop fought the guy trying to keep him away from the gun. Gun misfired and shot the black guy.
Black guy freaked and ran away.
Black guy changed his mind like 5 seconds later, turned around and started to go after the cop again, cop shot him then.
Witnesses saw the entire thing.
That is how I saw/heard of it.
This is how fox/cnn news aka "why the fuck are you listening to this crap" news stated it.
COP SHOOTS BLACK GUY! BOOM HEADSHOT!
