Mr. Monk Takes Manhattan - S3-E1
Trivia: When Monk is playing the 'find the queen' game with the crooked busker, one of the onlookers is Andy Breckman, the show's creator. He can be seen smiling in a close-up shot of him after Monk wins a second time. He has glasses, a beard and moustache, and is bald on top.
Mr. Monk and the Blackout - S3-E3
Trivia: The place where the "San Francisco Bicentennial Jamboree" is being held at is called the Landau Auditorium, another tribute to Andy Breckman's (the show's creator) wife, Beth Landau.
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.
