Illinois Gov. George Ryan shocked the nation when he commuted the death sentences of more than 150 inmates three days before he left office in 2003. In this interview, the Republican details his personal evolution from staunch supporter of capital punishment to ardent opponent. He also discusses his complicated legacy as a Nobel Peace Prize nominee who also served years in federal prison on corruption charges. His new book is called Until I Could Be Sure: How I Stopped the Death Penalty in Illinois.
