Mr. Monk's Favorite Show - S8-E1
Revealing mistake: The car that explodes isn't sitting in a striped parking lot space. In fact, it's very obviously parked out in the middle of the lot's traffic lane, well away from any other vehicles, precisely because the special effects crew are about to blow it up.
Mr. Monk and the Voodoo Curse - S8-E7
Revealing mistake: In the scene where the desks in the office are re-arranged, you can see that all the computers are on but none of them connect to any power point. NB: You can vaguely see that one of the computers is supposedly on Youtube while another is on Google Maps.
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.
