I think that's an important issue, and a national disgrace.
People who deserve execution should be legally executed, not turned over to prison inmates.
And until such time as our laws specifically state that brutalization by other prisoners is a part of incarceration, we should protect prisoners against each other.
Our prison systems are failures because criminals go in bad, but they can come out much worse. Aryan Nation, Mexican Mafia, Black gangs, it usually divides into a racial jungle for survival.
