Plot hole: Richard tells Tru that Carl periodically comes around threatening to exact revenge on him unless he pays him off. The audience eventually finds out that Richard hired Carl to kill his first wife, so it makes sense that Carl can demand money from Richard and not face any consequences. But why does the story make sense to Tru? The way Richard told it, Carl has nothing on him, so there's no reason for him to be paying him off. Tru should ask her father why he doesn't simply get a restraining order.
