A Christian perspective on the sentencing phase of the trial of Boston Marathon bomber Dzhokhar Tsarnaev. Not the only Christian perspective, of course. But one uniquely articulated by Schulder's two guests, Mark Osler and Jeanne Bishop. Osler is author of the book "Jesus on Death Row: The Trial of Jesus and American Capital Punishment." Bishop is a Cook County public defender whose pregnant sister and brother-in-law were murdered in a Chicago suburb 25 years ago. Her new book is entitled: "Change of Heart: Justice, Mercy and Making Peace with My Sister's Killer."
