Mr. Monk Bumps His Head - S4-E11
Continuity mistake: When Cora goes upstairs, her cat is curled up asleep in a chair. In the next, close-up shot, the cat is awake and sitting at the edge of the chair cushion, looking up at Monk with its front feet hanging over the side. When the shot cuts to wide angle again, kitty is instantly back in his original position, snoozing far from the edge and curled up against the pillows. (00:32:45)
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.
