Mr. Monk and the Naked Man - S6-E3
Plot hole: SPOILER Arlene Boras swaps Peter Magneri's MRI scans for those of a healthy person in order to hide the fact that he has a potentially lethal aortic aneurysm. Clearly visible on the MRI scans she is holding are the dates and times of the examination - and the name of the patient. Swapping the records is pointless.

Character mistake: SPOILER. Arlene Boras murders Vicki Deline in order to stop her telling Peter Magneri that he has an aortic aneurysm. Boras wants Magneri dead to clean up by short selling the stock in his company. Boras is a medical professional, and she would know that an aneurysm can burst if the patient is under stress or is shocked in some way. Allowing Deline to tell Magneri that he is in danger of dropping dead on the spot would kill him, which is exactly what she wants.

Factual error: While the police are investigating the murder at the start of the episode, the police make numerous mistakes with the crime scene. First there is no sheet over the body and/or tent to cover the body. Being they are on a beach it would make sense to cover the body from any debris or sand disturbing the body. Second, the sun is shining brightly would not help with preserving the body for the coroner. Finally why have the police only cordoned off a small area around the body. Being a crime scene and potential evidence could be found it makes little sense why they wouldn't cordon off the beach or most of it from the public.

Continuity mistake: While Monk and co. question Vicky's roommate, two throw pillows behind her on the couch shift their orientations several times from shot to shot. The larger one also moves from the couch corner to a spot behind the woman's left arm and then back again. (00:14:00)

Continuity mistake: A little white pillow on Natalie's couch falls over when Monk gets up, then rights itself again when he's in the kitchen. (00:31:15)
Mr. Monk and the Naked Man - S6-E3
Character mistake: SPOILER ALERT Monk accuses Arlene Boras of swapping Peter Magneri's X-rays in order to hide the fact that he has a potentially lethal aortic aneurysm. We see Magneri being examined and we see Boras handling his records, and they are not X-rays. Magneri was examined in an MRI scanner and Boras swaps the MRI scans - not X-rays.
Answer: The two men are trying to work out a secret deal between them without involving the union, which means the workers' interests aren't being represented and defeats the whole purpose of a union. The mayor would lose labor's support and Cusack's union troubles would just be starting.
