You could find a book implying anything. You seem to have a habit of putting whatever sexy scenario you find the most attractive into the Google search engine and immediately embracing whatever results you find, without even considering the possibility that the truth might be quite different.

It is almost nonsensical to even dignify with a response the suggestion that Tupac was killed for attempting to organize or unite the gangs. This is a man who literally got himself a MOB Piru tattoo in the months before his death, even though he had never grown up in Compton or done anything for that particular set. Are you familiar with LA gang politics? Do you know what it means to align yourself with a particular set? No one who is trying to establish unity or peace among the gangs for whatever nefarious purpose is in any hurry to get a gang tattoo, and they certainly aren't yelling MOB on record and wearing red clothing whenever they can.

Anyone who knows anything about Compton knows exactly who did this and why it was done. To suggest that the CIA recruited the South Side Crips to do this would sound insane to you if you were even remotely familiar with the backgrounds of these guys.
