On assumption it seems Pac let too many people get too close early in his career which came back to haunt him in the end on some Benny Blanco / Carlito's Way type shit.
In his move to Death Row he dissed the East Coast (not everybody, but a lot of artist.) & Bad Boy Records. He ran his mouth pretty big and some may view it as a stand up shit to be and be fearless, but truth of the matter is, he was dry snitching / exposing people he should of never of mentioned period. These people clearly make Suge Knight look like a bitch.
He fucked with some real black mafia people that put a hit on him after giving him a warning when he was shot in NY. He didn't listen and was put on ice as they say in the real mob world.
Yes, Makaveli: The Don Killuminati: The 7 Day Theory came out after his death, but who's to say there wasn't a snitch within the Death Row crowd taking back info on what was happening behind the scenes in the studio? What was being said in the songs? Where they would be at next? etc. Reporting back to Haitian Jack & Jimmy Henchmen.
Perhaps Orlando Anderson was placed in Las Vegas that night through these black mafia people on some Lee Harvey Oswald stand in to take the heat / attention off the others that were following the Death Row entourage. Perhaps these black mafia people extorted Death Row Records & their security and that's why the security were instructed not to be armed that night. I know it's a stretch (no pun intended), but it's clear these black mafia people were heavily involved within the music industry in L.A. (Beverly Hills / Sherman Oaks home of Death Row Records) as well as NY.
In the end, with all this news coming forward, the death of Tupac Amaru Shakur appears to be a true mafia hit outside Bad Boy Records & The East Coast / West Coast so called war.
