When Steve Burden decides to give up his deputy badge, he's shown looking at it pinned to the pocket of his shirt. In the very next scene, when he actually removes it, it's located next to, but not on, the pocket of his shirt.
The walls of Dennison's office building appear to be made of panels painted to look like bricks, rather than being of a solid brick construction, as observed when Willis tries to kill Burden and Kane.
In two scenes, there are cart tracks on the ground from previous takes: when Larry brings his father's body to town and when Burden brings Kane back to town.
