When it comes to the death penalty, a majority of Americans prefer life without parole sentences for people who commit crimes. But for some offenders, a sentence to die behind bars is a disproportionate punishment. Life without parole for juveniles has already been ruled unconstitutional. A case pending before the Supreme Court will decide whether life without parole for non-violent offenders is also unconstitutional. The broader issue is that sentences should be proportionate to the crime and should account for any diminished culpability of the person who committed the crime.
