When Jim and Patsy flee the farm, there are fingerprints in the dust on the car from previous takes.
When Lianne visits Jim's trailer after he's been jumped by Anthony Boy and Syl, we see that the phone has been knocked off of the hook. While Jim and Lianne talk, the phone rings and Jim answers it without having hung up the extension. Leanne placed the phone on the hook before lighting her cigarette.
In the first scene an armed suspect is firing from the house with police officers ducking behind cars for cover but bystanders are standing around without any fear for their safety; the cops weren't doing anything about it either. (Note: The crowd of spectators being present at the shooting was to show how police "groupie" Lianne Sweeney considered herself "part of the gang" by "assisting in crowd control" - as she later explained to the shooting review board).
