Captain Defenestrator

Mr. Monk Stays in Bed - S4-E3

Plot hole: When Stottlemeyer and the other cops arrive at the recycling center, the patrol car's siren turns on and off. The killer had said to Monk that if he called the cops, he'd kill Natalie. Coming to a hostage situation with the siren going would be a really bad idea. (00:37:45)

Captain Defenestrator

Mr. Monk and the Genius - S7-E2

Plot hole: Kloster's plan of switching the headstones wouldn't have worked because cemeteries keep records of who's buried in which plot. Before exhuming the body, the records would have been checked and someone would have noticed that the name on the headstone and the name in the records didn't match. (He might have broken into the office and changed the records, but it's never brought up, so he likely didn't.)

Mr. Monk and the End - Part I - S8-E15

Plot hole: When Randy tells Captain Stottlemeyer that the killer shot the train station announcer and took his jacket and ID, the microphone in the room is still active and everyone in the station hears Randy's conversation. If that's the case, then why didn't everyone in the station hear the gunshot? Even if the killer used a silencer, he would have made noise taking the announcer's jacket and changing his disguise, which would sound like a struggle over the open mic anyway, and it would make no sense to turn it on after killing the man. (00:29:00 - 00:30:00)

Captain Defenestrator

Mr. Monk and the Really, Really Dead Guy - S5-E15

Plot hole: In this episode, Monk doesn't know to open a cell phone to answer it, but in "Mr. Monk and the Kid", he used a cell phone with the ransom drop with no problems. (00:04:25 - 00:05:05)
