Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk and Natalie are talking to Kemp in his office, the desk ornament and the cup of pencils that Monk keeps organizing change positions between shots. In the shots from Monk's side of the desk, the ornament is closer to the door. In the shots from Kemp's side, the pencil cup is closer. (00:09:40 - 00:11:20)
Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk is trying to join the two cops' conversation about football, in the shots from the side of the police car that they're standing near, the two cops are standing less than a foot apart. In the shots from the other side of the car, they're far apart enough for Monk, Natalie, and Captain Stottlemeyer to stand between them. (00:03:00 - 00:05:00)
Answer: Stottlemeyer was already upset after the phone call. He was trying to get "Kevin" (who would have to be a judge, but no further character information is given) to issue a restraining order with no evidence of needing one, except that Adrian Monk said she needs one. Kevin said he would need to "sleep on it." So it's clear they've been trying to provide protection and unable to get the results they need, which seems to be based on no one trusting Monk the way Stottlemeyer does. He's just angry that they failed to protect Linda despite all their work. Although it does feel like a scene was cut, or altered, from the show that shows the futile attempts to protect Linda which built up to his outrage.
