Mr. Monk and the Candidate (2) - S1-E2
Other mistake: When Monk is climbing the ladder to pursue the killer, at a couple of points, he wipes a rung, then grabs the one above it. (00:18:15)
Mr. Monk Goes to the Carnival - S1-E5
Other mistake: Kitty, the killer, is seen running to Gitomer after Lt. Kirk leaves him. She is supposedly running to stab him, but you can see that both of her hands are empty as she dashes to his side.
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.
