David talks with Maurice Possley, a Pulitzer Prize winning journalist, about exonerations – the cases of people sentenced to a prison term, sometimes for life, sometimes for death, for a crime they didn’t commit. His work on this subject was influential in the decision of the governor of Illinois to commute the death sentences in his state, and also in the abolition of the death penalty there in 2011. Maurice Possley is the Senior Researcher for the National Registry of Exonerations and also writes for the Marshal Project. Read more about his work at: http://www.mauricepossley.com
