First one is that he got killed by some gang/gang member, most probably because he fucked somebody's girl, owed someone money, or just simply because he was disliked by them.
this is a very poor reason to kill the most succesful and most powerful rapper in the world. even if someone had this idea in mind, it wouldn't be as simple as it sounds. this simply cannot be THE reason he got killed for. ofcourse everything could be a possibility but there's no evidence whatsoever to back that up.
and i'm so glad you posted that video because i've never in my life seen a video like that. i actually have viewed that interview about 4 to 5 times just because i love his honesty. i could listen to him for hours because he knows what he's saying. and the amount of facts he states in his words are astonishing and this just goes the show that he was smarter than people thought he was. people looked at him and thought "just another thug with tattoos all over him, he's here because people got him here and he has so much money bla bla bla" but there was a true honest man behind all of that. and that's why he got killed, because he could change the world. i believe they got rid of him because he had the power to make a difference. he knew that, so did the government.
