Cyntoia Brown Clemency: Lawmakers to Re-Examine Tennessee's Juvenile Sentencing Laws

Pennsylvania was one of several states to create a mechanism to review sentences of every inmate serving life in prison. Of the 535 men and women serving life for crimes committed as juveniles, 250 were re-sentenced and 150 released, said Marsha Levick, chief legal officer with Juvenile Law Center. 

"Most states took their responsibility seriously" after the Supreme Court rulings, she said. "It's been a mixed bag of responses, and some have been stunningly slow to act, but all of them make Tennessee look very much like an outlier."
