No offense breh, but I don't think you understand prison culture. You can't be a ChoMo in federal prison. Period. There are people that would foam at the mouth to get an opportunity to smoke someone like Kells. You got cats doing multiple life sentences with no parole, and they have nothing to lose. What's another life sentence? Now, on the flip side, Kells has money, and could pay other gang members for protection.
Chances are none of this is gonna be an issue anyways. He's not gonna be allowed in GP. They're gonna put him in PC or the SHU for sure. I can't imagine someone with his level of fame and the charges he's been convicted on being allowed to go into general population.
Which is almost worse. Dude is gonna live in solitary confinement locked down 23 and 1 in a small box for so many years.
