Beef in general didn't get Pac killed. Even if you buy the theory that Orlando killed Pac, it still wasn't over beef, rather getting his ass kicked.
If Suge killed him, how was it still beef that got him killed, when to our knowledge, there was no beef between them. If there had been beef between Suge and Pac, do you think Pac woulda even been with Suge that night? Hell no. Pac didn't even want to go to the fight, Suge talked him into it. Pac wanted to go to Atlanta and solve some family problems.
I don't know anything more than the average Pac fan does. My "Suge Killed Pac" theory is based off of commonly known facts surrouding Pac, Suge and the things that happened both leading up to that night as well as that night. And if you mean it's a "closed case", I don't think it is. Last time I checked it was open, and a case being closed doesn't mean shit other than they've given up on it.
Don't be stupid.
