1. The prosecutor has the right to order prohibition and crowding. In the legal system, prosecutors are endowed with important power and status, and their main duties are to prosecute criminal acts on behalf of the state and supervise the trial process of the court. This authority makes prosecutors have a high deterrent in the police and other law enforcement agencies.
2. Prosecutors can act as a shield to prevent supervision by procuratorial, taxation and financial supervision departments. In the process of performing their duties, the police may need to cooperate with these departments, and the existence of prosecutors can ensure the smooth progress of this cooperation, and at the same time, it can protect the police from interference or investigation by these departments to a certain extent.
These reasons may be related to the fear of prosecutors by Korean police, but please note that this does not mean that all police are afraid of prosecutors. Everyone's personality and experience will be different, and their attitude towards different situations will be different.
