In 1976, Dallas police officer Robert Wood was shot and killed during a routine traffic violation stop. For 12 years, the killer remained at large while an innocent bystander by the name of Randall Adams was wrongfully convicted for the murder and was at one point sentenced to death. In 1988, a documentary about the case resulted in public outcry for a new trial. Multiple inconsistencies during the process of the trial were noted, and in 1989, the Texas appeals court granted Mr. Adams a new trial. Shortly after, he was released and all charges against him were dropped.
The actual murderer of the police officer was later executed for committing another unrelated murder. In a way, this documentary was the predecessor of later popular true crime documentaries such as “Making a Murderer”, “The Jinx”, and “Evil Genius”. During the initial murder trial against Adams, the prosecutor commented in his closing argument that the police are the “thin blue line” separating society from anarchy. The released documentary therefore took this line as its title. While the prosecutor did not create this phrase, the documentary did popularize it, and it’s now closely associated with the important role our police force . . .
