Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight in the kitchen, piles of plates are knocked to the floor. The plates that we see hitting the ground all remain intact. Nevertheless, we hear the sound of plates smashing, and when the aftermath is shown, there is broken crockery everywhere. Clearly the plates used were made of plastic or some other unbreakable substance to minimise injury to the actors and stuntmen.

Revealing mistake: During the fight scene in the restaurant kitchen you can see that the woman is a stuntman, you can even see the horrible wig pop up off the stuntman's head a few times.






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.
