The badge Earl finds changes from having a pin to a clip between scenes.
When Earl steals the badge, is has a leather backing. When Earl picks the badge up from the water, there's no backing on it, later the backing reappears on the badge.
Right after Officer Daniels uncuffs Earl, he pulls Earl's list out of his shirt pocket. He hands the list to Earl and it is crumpled into a ball. When the camera cuts to Earl with the list, it is neatly folded.
At the end of the scene where Earl confronts Officer Stuart Daniels at the bowling alley while trying to get Creepy Rodney arrested, you can see the pink tape spike used to mark where the actors are meant to stand.
