The Thin Blue Line: The Film That Freed an Innocent Man

Dallas, 1976. A police officer is shot dead during a routine traffic stop. The killer drives away into the night. Within months, a man is sentenced for the crime. But was he the right man?

Errol Morris's 1988 documentary The Thin Blue Line follows the murder of Dallas officer Robert Wood and the conviction of Randall Dale Adams. Morris sat down with the key players, including the man who was with Adams that night. He didn't stack up neat talking heads. He built a hypnotic, stylized reconstruction of the night in question, set to a haunting Philip Glass score.

What makes it stand out? The film doesn't just retell a case. It picks it apart. Witnesses contradict themselves. Stories shift. Morris lets the people at the center of the case talk, and the cracks show on their own. Adams was convicted and sentenced to death, and the film became part of the fight over whether that verdict could stand. Adams was later released, and the documentary is widely credited with helping make that happen.

It also reshaped true crime itself. Nearly every investigative doc you binge today owes it a debt. So watch it with one question in mind: how does a system this sure of itself get it this wrong?
