A. The only proof of him prophecising anything is in his lyrics and his interviews. Watch them, he constantly talks about how is going to die soon, how he knows he'll die soon, etc. I never said that he successfully did it, but he did predict his own death. Watch the video for "Aint Mad at 'Cha". The video depicts his death almost in the exact way that it did happen. The only difference in fact, is that it isnt after a tyson fight I dont think.
B. It can't be proven that he died because there is no body. Nobody can actually dig up his grave or take DNA tests and prove that he is in fact dead. People close to him and others do say that he is dead, and again I never said that I believed he was alive, but their word isnt enough for solid undeniable proof.
Tupac was shot in 1996 on a Las Vegas strip after a Mike Tyson fight. One of the most busy streets in Las Vegas. There were literally hundreds of people on the sidewalks, and Tupac was in an entourage of cars. There were about 10 other cars lined up behind him. His car came to a stop at a red light on Koval and Flamingo intersections, and a white Cadillac pulled up beside him. Shots were fired, and the confusion starts here. There's conflicting stories from both Suge Knight (the person who was actually in the car with Tupac when it happened), his bodyguards, the Outlawz (the people who saw him shot directly in front of them), to his own mother. There are also suspiscious things about his death that have yet to go unanswered officially, and an autopsy picture was leaked onto the internet but was proven to be false. If you're interested in finding out more about it and the suspiscious consequences behind his death, read up about it, there's literally tons of sites out there that have detailed information on anything suspiscious. Some of them are lame, but some of them are actually true and cannot be explained away other than the fact that something is going on. Just read about it. "Tupac Alive Theories".
