"I'm not an angel," sings one, "but I'm not the devil."\xa0Filmed at an independent TEDx event inside Muncy State Prison,\xa0it's a rare and poignant look inside the world of people imprisoned with no hope of parole. (Note: The prison's Office of Victim Advocacy has ensured that victims were treated fairly and respectfully around this TEDx event.)
