It's been 50 years since "Mister Rogers' Neighborhood" first went on the air – a television program for young children that treated them with respect, and helped them understand a complicated, often challenging world. Faith Salie looks back on the exceptional Fred Rogers, talking with his family and collaborators, and with filmmaker Morgan Neville, director of a new documentary, "Won't You Be My Neighbor." Air Date: May 27, 2018
