What you said upstairs makes sense, but Lin Guiren in the movie "Tokyo Raiders" is wearing a Japanese police uniform, which means he belongs to the Metropolitan Police Department, while Lin Guiren in the movie "Hancheng Raiders" belongs to The Special Detective Team of Japan’s Defense and Foreign Affairs Section. The question raised by the poster is very professional. The organization “Special Detective Team of Japan’s Defense and Foreign Affairs Section” does not exist, but there is a similar police agency organization called “Japan Police Department Special High School Section”. "The abbreviation of "Tigao" is similar to my country's "National Security Bureau" which is subordinate to the Ministry of Public Security, but is independent of the public security system and directly under the Ministry of Public Security. "Super High School" was the name during the war. Now it seems to be called "Public Security Section" to distinguish it from the "terrifying special high school" during the war. However, the Japanese people are still accustomed to calling this type of police officers "special high school" and they belong directly to the police. The Office of the Inspector General is not part of the police system. Its responsibilities are to internally monitor and control left-wing elements who are dissatisfied with the government in the country, monitor the intelligence assets of foreign forces, and externally monitor government employees who may be engaged in espionage or intelligence transactions, etc. As the times change, this The agency also cooperates with Interpol to jointly combat transnational crime.
Don’t judge from the literal meaning: 1. If he belongs to the Ministry of Defense, he will be a self-defense officer or intelligence officer of the Self-Defense Forces, and he will wear military uniforms instead of police uniforms. 2. The name "Special Detective Team of Japan's Defense and Foreign Affairs Section" sounds very bluffing, but friends who know Japan or people who have lived in Japan can easily find that Japanese people are very good at naming. For example, if a murder occurs in a certain place in Japan, then In order to handle the case, the local police will set up a task force. This task force may be called the "Special Detective Team for the Murder Case in a Certain Place", while the "Japan Defense and Foreign Affairs Division Special Detective Team" is named based on the nature of the case it is investigating. The name is not a special organization.
So to sum up: Lin Guiren is a police officer of the Japan Metropolitan Police Department. This is for sure, just like a police officer being assigned to the homicide team or the anti-drug team.
