Got you...he goes into detail about all the dirt he's done in his life in his book mentions the incidents you linked too and talks about rolling around with 1/2 ki to snort and mentions Zip alot and only mentions Jimmy in passing really...he talks about his relationship with Pac and the media tries to play up like him and Pac were boys but his inner circle were the dudes who gave Pac that work on both occassions
He did tell Pac that he knew them nikkas and to stop hanging with them
