Jeffrey Dahmer was beaten to death in a Maximum Security Prison. Granted, he had a cellmate, but that's the guy who did it...
Won't matter how much FDOC wants to protect him. Unless they put him in a SuperMax, someone will have a chance at him if they want one. The only question will be...will they?
Usually, the retribution jailhouse murders are for victimizers of others. I dunno how that would apply to a guy who killed his own children, as heinous as that is, and it IS grossly heinous.
Not being a hardened criminal on death row... I just don't have much insight into the politics of that mindset...
