Such a sentence is inhuman and probably unconstitutional. DEATH BY OLD AGE! (With 3 squares a day, cable tv, free medical care, free housing). The mind boggles at such a draconian sentence!
I agree. If we are convinced, beyond reasonable doubt, that this guy should never, ever, live in society again, then he needs to die. There is no point in prolonging the death sentence, or making it seem more civilized because we aren't going to do the killing; we are going to let the time do it.
