I think it should be clarified that what they are deciding is if Life in Prison without the possibility of parole is constitutional for a juvenile convicted of a non-homicide crime.
It isn't about releasing these 2, but rather, whether or not they should ever be allowed to have their sentence reviewed.
The one who was 13 at the time of the crime has been in jail for 21 years (for rape). I don't think anyone could argue that a 30, 40, or even 50 years sentence is justified, but he has been given what amounts to a death sentence.
The other ( the 17 year old) was given life without parole for armed robbery.
Again, the question is not should they be let go, but only that at some point they should be able to come before a parole board.
