so that rules out the suge pulled the trigger theory
Not necessarily because the bodyguard did not see what happened in the car. The bodyguard was in a appauled shock, he said he didn't know if they were alive or dead, he just guessed. Then Suge could've told the other dudes to just "shoot the car" and he'll take car of the rest. So they probably shot up the car and none of the bullets probably touched them and Suge probably shot Pac from the inside then grazed himself with a shell and laid out. Why was the police arresting Suge if they seen him in a shot up car next to a half-dead bleeding to death half-conscious man? Why didn't Suge take the normal route? Why wasn't everything done as normal? Pac probably was in too much shock that his own homey shot him to say for it even to register in his mind while bleeding to death for him to even say it. He probably had that look on his face like when Cam (Alpo/Rico) shot Mckhei (Mitch/Rich Porter) in the Paid In Full movie... That shocked look.
