I have find it seriously difficult to believe the kid went for a toy gun when a cop pointing his gun at him.
That's my opinion on the matter. It's same opinion that cops were too eager to fire on Amadou Diallo. I really doubt he was pulling out his wallet in an attempt to kill the police. Pulling a fake gun is just as incomprehensible as pulling out a wallet.
