If you recognize the name Sister Helen Prejean, it’s likely from the book or film “Dead Man Walking.” This Roman Catholic nun’s correspondence with a death row inmate inspired those works and also led her to become a leading advocate against capital punishment. Prejean is in Birmingham Monday, with a viewpoint she says has deepened through her more than two decades of advocacy. She told WBHM’s Andrew Yeager, she sees the legacy of slavery in today’s criminal justice system.
