Mr. Monk and the Panic Room - S3-E2
Factual error: The cops gain entry to the panic room to be faced with a chimp waving around a loaded handgun, apparently having shot a man, and shrug and make jokes about reading him his rights, instead of expressing the slightest concern that this animal might shoot them. Cops shoot remotely aggressive dogs all the time, but an ape with a gun doesn't even make them raise an eyebrow. Plus the police never did a gunshot residue test on the chimp. Standard procedure, and would've proven they didn't shoot.
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.
