I think you meant gridlock, because there are no clues in gangrelated, just little comments that pac makes , that make you wonder about his real life. The odds are high, but when pac said: "We can make it look gang related", i actually believe he was telling us something.
Anybody can make something look gangrelated and what went down in vegas, is proof of that. Pac is not stupid, so i dont think he will fight a gang member and think nothing will happen to him, also, the thing about nobody having any guns that night, is wierd too, not to mention that, why didnt the killers shooting everybody in that line of cars?
Pac and suge was not the only ones involved in that fight in the lobby. So all and all, the whole thing in vegas seems planned. So pac made it look gangrelated and left, thats it.
