It works now. I dunno if it was a real diss or not we probably will never know the truth, but the things is he started to perfom it in concerts as a diss towards pac.
I think Biggie wrote the song becoz he heard the streetz saying he had sumthing to do with Pac's shooting,so he wanted to find out from Pac,who shot him.thats what I think
i saw a video years ago of this reporter dude going around hes nieghborhood asking ppl that knew biggie closely if he sold drugs as well as other stuff and they all said no. they also said he had never evan been in a fight before.
