The Thin Blue Line is a documentary made in 1988. Not only did this film win several awards, but also brought the release of an innocent man on death row. This movie is hailed as the first mystery movie to actually solve a murder.
This film is about the murder of Dallas police officer, Robert W. Wood, on November 28, 1976. Wood was pulling over a car for not having headlights on. Once Wood walked up to the car, the man driving pulled out a gun and shot Wood to death.
The only information the Dallas Police Department had was the model of the car, and they weren’t able to make an arrest. Then 16 year old David Ray Harris gave the police information. Harris told his friends he was responsible for the crime. Later Harris told police he was just bragging and that he didn’t really commit the murder.
Harris led police to the car that was driven from the scene of the crime and the revolver that he identified as the murder weapon. Harris blamed the murder on a man he spent a little time with during the evening of the murder named Randall Dale Adams who was 28.
Adam’s car ran out of gas and Harris offered to give him a lift. The two parted ways before the murder occurred. Both were questioned about that night and their timelines didn’t match up. Although there wasn’t much evidence against Adams, it was easier to convict him because he was older than Harris and could be given the death penalty for the crime. A few witnesses came forward and claimed to have seen Adams shoot the officer. Adam’s was convicted and given the death penalty.
The film’s investigation showed that five witnesses had committed perjury. Adams had his conviction overturned and the case was returned to Dallas County for a retrial. The case wasn’t prosecuted again and Adams was subsequently ordered released as a result of a habeas corpus hearing in 1989.
Adams was on Death Row before this documentary was released. If this film was never made there is a very good chance Adam’s would have died and been wrongly convicted his entire life. This documentary made a huge impact in the film world and to Randall Dale Adam's.
