The Introduction Of Miranda Rights
In the film, Red claims that Andy escaped from Shawshank in 1966. This was the same year that the Supreme Court heard the classic Miranda v. Arizona case. This decision established the requirement that a defendant be notified of his or her rights when being detained. As a result, at the end of the film, when the cops arrest Captain Hadley, they can be heard reading him his Miranda rights. This contributed to historical accuracy.
