If he was he would've already done so and Diddy would be in cuffs.I'm still waiting to see if Keefe D points the finger at him though.
I mean how could he even prove it he said he randomly saw Pac and wheeled around and passed the gun to Baby Lane and that Diddy hd a bounty that he wanted to collect. Pac died because he beat up Baby Lane not because Diddy gave the order.
