Other mistake: Fraker's footprints are right next to each other in Kersey's bedroom. The right footprints even with the left footprints. The only way for this to be possible is if he had hopped around the room rather than walking.

Continuity mistake: When Kersey goes into the post office and his girl is waiting in the car, Fraker and his goon knock her out and shove the car down the hill. As it goes down there is a view of the back of the car and the reverse lights are on. Then as it is about to hit the other car, the lights are now off.
Richard Shriker: I can't do anything. I'm a cop.
Trivia: The bad guy, Fraker, real name Gavan O'Herlihy, is the lost son "Chuck Cunningham" on the first season of Happy Days in 1974.
