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: 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.

Continuity: A little white pillow on Natalie's couch falls over when Monk gets up, then rights itself again when he's in the kitchen.

Plot hole: There is a dead body on the beach, police all around and none of the public are even curious at the crime scene. There is quite a number of people at the beach and only a few people even take a glance at the body which is additionally uncovered. If there was no one around then it could be understandable, but the fact that no member of the public is even trying to look or even upset by this is just impossible to believe.
