Hey, what’s wrong about that? Only thing better would be to give each one a claw-hammer and tell em the one that survives will be set free, then shot that SOB.
I don’t have a problem with allowing gang bangers to kill each other in prison. But, there’s the possibility that a person who is in prison for some lesser crime, who perhaps stole in order to feed his starving children, being pitted against some gang banger just for sport. I have a problem with that.
