Other mistake: Inevitably the officers have to concisely give to the quirky inspector a quick profile of the suspect. For their "background checks" they read from profile sheets. It is unclear if they wrote them themselves or not; sometimes especially in earlier seasons they seem to receive them. These sheets contain sentences often written in a rather informal tone that does not fit the format, and in fact often you can see that whatever the officer is saying in casual tone as if it were part of the dialogue is written verbatim on the sheet itself. Example; 6-8, when Florence says "He's big on family values and promoting education in the community", with her line already readable word for word on the sheet in Jack's hand in the previous shot.

Continuity mistake: When Aunt Mary is writing on the whiteboard at the hospital, the word "killed" changes style between shots. (00:31:40)
DI Jack Mooney: My grandfather told me a story once, about these two wolves fighting inside all of us. And one of them is anger, envy, self-pity, regret. The other one is love, truth, faith, hope, that sort of thing.
And I asked him "which one of the wolves would win?" And do you know what he said?
"The one you feed." (00:18:15)
Question: Why don't they even think of pretending the victim just drunkenly tripped in the kitchen while getting a sandwich, and his sister-in-law reflexively tried to catch him, unfortunately holding a knife? He thought he would live a few more minutes, so he could have backed up the story. Instead, everybody (victim and police) just takes it as given that the stabbing will reveal their relationship.
