Mr. Monk Goes to Vegas - S3-E14

Continuity mistake: After Monk tells Randy to hit whilst playing Blackjack, the dealer gives him the Three of Spades. The dealer places it a bit to the right and over the Eight of Spades. The next shot we see of the cards the Three is now completely over the Eight and we can only see a bit of the bottom of the Eight.

Continuity mistake: The stacks of chips Monk bets when the dealer says they can't cover that change when Mr. Thorn says they can. Some stacks are shorter and have different colors on top. They change again when Monk figures out the case.
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.
