Our criminal justice isn't about rehabilitating a person, its more about retribution and keeping them out of the society. If he gets the full 15 years and stays for full 15 years, will he have learned anything or change his attitude? Probably not. Years of punishment is so arbitrary it makes no sense to me. Will he ever get any training or instruction that his way of thinking is wrong...

Well this is a cycling site so I will stop here. I hope he spends the next 15 years in prison though.
