The first describes the development of an oppressive bureaucratic force allied with the military to crush any signs of unrest fomented by the urban proletariat in 19th-century Prussia, while the second discusses the gradual takeover of the German police by agents of the National Socialist movement, thereby creating the prime agent for consolidating the totalitarian State. In addition to providing information on the historical evolution of German institutions, these books analyze the relationship between police, the reigning political order, social processes, and military institutions. Both authors note the importance to police forces of public legitimacy in order to operate effectively. Finally, the authors recognize the influence that organizational structures can have on police operations.
