Mr. Monk and the Three Julies - S6-E13
Plot hole: There is no other reason for Randy to hand Natalie the walkie-talkie but to fill that plot hole. He is in fact in breach of police rules when he hands his department issued radio to a civilian to answer it while he is on duty. The same goes for Stottlemeyer and the car keys he hands to Monk. Even more so since he knows Monk could not even drive that car to the side in the far fetched scenario that a police car had to be moved while the cop is serving a warrant inside the building the car is parked in front of.

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.
