<he will not be attacked by his fellow brothers, like whites are>

actually, the more heinous the violent crimes(with exception of pedophilia) are committed(i.e. the butchering of ron and nicole here), the more respect is usually given to the prison thug who committed them. Pedophiles on the other hand, although they've committed a violent, heinous crime against kids, are usually beaten, abused and in some cases killed while in prison. Even twisted criminals can't stand to be identified with them. Those who attack women as well.
It may depend on how much exposure OJ has to the the other thugs he is in with, as to his outcome.
