In an attempt to recreate a scene from GTA...what did he think would happen after he managed to kill the guy. Oh wait, the police follow scenes like this, right? And...they chase you down until they either kill you or arrest you. I guess he didn't think it to the end, huh...must have stopped at "I'll drive off really really fast! Yeah, it'll work if I drive really really fast".
"I let my pants hang low...I'm from the hood and that's how shit go!"
