Trivia: Brooke Adams, Tony Shalhoub's real-life wife, has appeared on the show 5 times. In S1 as Leigh the flight attendant Monk drives crazy in "Mr. Monk and the Airplane"; in S3 as Mrs. Carlyle in "Mr. Monk and the Kid"; in S5 as Sheriff Butterfield in "Mr. Monk Visits a Farm"; in S7, again, as Leigh the flight attendant in "Mr. Monk's 100th Case"; in S8 as the crazy cat lady in "Mr. Monk and the Badge."
Trivia: Leland Stottlemeyer and Randy Disher (named Randy Deacon in the pilot episode) were named for Inspector Lestrade in the Sherlock Holmes series. Take the first two letters of their names (LEland STottlemeyer, RAndy DEacon), and they spell LESTRADE.
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.
