Tick...tick...tick... (1970)

Plot hole: At the end of the movie, the sheriff is going home and gives his deputy and the mayor a ride home. They pass over a bridge with a sign that says 'Leaving Colusa County'. Surely they don't live outside the county?

Other mistake: The siren changes from manual to electronic as the newly elected sheriff rides through town on his first night. Also during this ride is a reflection on the windshield of a dash light which the car isn't equipped with.
