    Produced by Vox senior producer Joss Fong, False Positive is a 30-minute documentary, split into three episodes, focusing on the conviction of Robert Lee Stinson.

    Stinson spent 23 years in a Wisconsin prison for murder after two forensic odontologists concluded that his teeth matched bite marks found on the body of the victim.

    False Positive looks at the structural and cultural factors that have made the U.S. criminal justice system susceptible to unreliable forensic science, and that continue to impede progress toward more reliable methods today.

    We take a look at his trial in part two. Watch here:

    And the story concludes in part 3:

    Most science is scuff politicized science. Global warming for example.

    I understand the context of the situation and that the theory of what his teeth would be like, but bite marks are very unreliable evidence.

    you should probably make both part 1 and part 2 have the same title because that is very confusing

    I remembered Ted Bundy. The lawyer brought a picture of the examined body with bite marks. The bite marks looked like it came from Ted Bundy.

    Usually the detectives have the suspect bite on an object then they would compare the bite mark to the actual bite mark from the crime scene.
