Factual error: The criminologist describes the events of the movie as taking place "on a late November evening". In the very next scene, Brad and Janet are driving in Brad's car, and President Richard Nixon's resignation speech is playing on the radio. Nixon resigned in August of 1974. (00:12:00)
Suggested correction: It is said by the writer of the movie that Brad taped the Nixon speech so he could listen to it later in his car, the movie does take place in late November.
