Mr. Monk Makes the Playoffs - S7-E13
Other mistake: At the end when Bob Costas is signing off, the mic is in his right hand with the window on his right). When it switches to Natalie watching the upside down TV, the image on the screen is a flipped image (so that the mic is in his left hand and window is on his left). The broadcast wouldn't be a flipped (or mirrored) image than what we see, otherwise, everything the viewer is watching would be backwards (like the writing and numbers).
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.
