Legal analysis: the difference between political commissar and secretary of public security bureau: the secretary is the post of the party, and the political commissar is the administrative post. The public security organs implement the chief executive responsibility system, that is, the director is the top leader; Administrative organs such as towns, counties, cities and provinces implement the responsibility system of party committees, with the party secretary as the head; The political commissar of the public security bureau is generally the deputy secretary, who is in charge of the ideological and political work and party work of the unit and is the second in command. The party secretary of the public security bureau has real power. In reality, county-level public security organs will set up political commissar posts. Regardless of the director's political commissar, there will always be a party secretary and a deputy secretary. When the political commissar is the party secretary, then the political commissar must be concurrently held by the Standing Committee of the county party committee. When the section chief is the party secretary, he must be a member of the Standing Committee of the county party committee or a deputy county magistrate.

Legal basis: Article 4 of the Regulations on the Organization and Management of Public Security Organs, public security organs implement the responsibility system of the chief executive.
