Who would he have collecting for him though? All of his "people" flipped and wrote books. Those who didn't are still in prison or dead. And that still leaves the question of how will that money get back to him, in all of the places he supposedly was, according to the FBI, without leaving a paper trail. There's really no indication of how he got the money or where it was from. It's easy to get guns, so thats not such a mystery.
