Mr. Monk and the Airplane - S1-E13
Continuity mistake: "Nationwide Airways" is the name of the fictional carrier used in the episode, and it even has its own logo and livery. Yet in the exterior shot of the plane pushing back from the gate, it has suddenly transformed itself into a Delta Air Lines plane. It also looks like a 1990s Delta plane while it is taking off.

Mr. Monk and the Airplane - S1-E13
Factual error: Though anti-freeze is lethal it does not kill quietly and fast but rather agonizingly, painfully and slowly, inducing vomiting and fever. (00:30:30)
Mr. Monk and the Airplane - S1-E13
Factual error: When the flight attendant announces that "they have been asked to return to the gate" the French pilot and his mistress are already celebrating with a glass of wine, but that is impossible since drinks are only served after the take off phase when the plane has reached its traveling altitude.

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.
