Inspector Kenmochi the Murderer File 2 - S1-E20
Plot hole: One of the plot points of the episode lies in the fact that Kenmochi is accused to be the killer because only the cops had Busujima's phone number, apart from his two accomplices. That point holds absolutely no weight; the killer is a killer because he, well, killed someone, and that someone was exactly one of those accomplices. It's a fact that can't be ignored by even the most ignorant investigator, especially with the accomplice's phone being directly involved in the murder. (00:10:15)
Inspector Kenmochi the Murderer File 2 - S1-E20
Plot hole: The brief intermission when Busujima meets the 'killer', or at least the person wearing the hat, does not make sense plot-wise and is merely a dishonest way to trick the audience. It's not even something Busujima tells someone, so it can't be characterized as a 'unreliable narrator' device. (00:18:30)
