Innocence Project channel on YouTube
The Innocence Project has a great account on YouTube where you'll find many interviews with exonerees, as well as video of events like the April 2007 ceremony (embedded below) where 17 people who served decades in prison for crimes they did not commit are honored. Please watch the video below for an introduction to their stories, and visit the Innocence Project on YouTube here.
