Viewers of the show "Making a Murderer" learned about the Wisconsin Innocence Project, which works to free wrongfully convicted individuals. Texas A&M's law school operates a similar program known as its Innocence Clinic. Here, students have the chance to work on actual cases where convicted criminals claim their innocence. "The Sound of the Spirit" interviewed professor Mike Ware, who runs the Innocence Clinic at the Texas A&M School of Law about "Making a Murderer" and another case, the San Antonio Four.
