Continuity mistake: Wheb Hamilton shows up to talk to Chris after he's been attacked, we see Chris unload some wood from his truck, then belt on a tool belt. After belting it on, he pulls his shirt out from under the belt and we see his stomach. There are no scars on his stomach from the earlier attack on him. Later in the courtroom, Chris opens his shirt and we see scars from his collarbone to below his navel.
Continuity mistake: After Chris becomes Sheriff we see him pull Hamilton over in his car. As they are talking the camera cuts to the far side of the car where we can see the girl in the passenger seat. She is facing forward at the road, and then when the camera cuts again from behind Chris we see that she is now looking at Chris.
