Maximum security inmates have limited general population time. Child killers are oftentimes in protective custody for their own safety. If they happen to share a cell with another inmate, there is something called "prison justice" that is pervasive throughout the system, there is a good chance the inmate sharing his cell will get a shot at meting out that justice. You'll never hear about it, but the inmate system has a way of punishing child killers and child molesters (CoMos).
