The reason they shot him is because he crossed the officers reactionary gap with a weapon ....... Cliffs, they were justifiedNot sure this is a report yet but this cell phone video surfaced 5 days ago.
25 year old Black male stole 2 Energy Drinks and waited for police to come arrest him, while he yells "shoot me", while pasting towards police, infront of a audience who where basically supporting him.

IMO he was stupid and even though he didn't make it 3 feet from the cops, I'm not surprised of what happen. He shouldn't have went 'crazy' and tried showing off while they got a camera(s) rolling with bystanders who where getting him going even more. He was old enough to know better. I guess he really was standing around talking to himself as the news stated. No knife found though.
EDIT- I heard one of the bystanders who said "drop it bro" when police told him to "drop the knife". So I guess he was packin'.
