Barely seventy years ago a Berlin Chief State Prosecutor said in the course of a political trial what has become a household word: the State Prosecutor's Office is the most objective authority in the world (1). Within this self-concept of the German State Prosecutor's Office, which is typical and has lasted up to our own day, we can find the whole problem-area covered by this paper. But the gap that can yawn between idea and reality is clearly recognized in the critical view-point adopted by modern criminology. According to this, questions of power and judgment, of social class and equality, and of the use of the law and criminalization come into view. However, much these matters may appear to many people to be provocatively chosen, and formed according to counter-ideological ideas; nevertheless they are important and no longer to be thought out of existence in modern discussion. In traditional, positivist criminology the system of penal control and those who carried it out were not a topic of discussion. As is well known, the area considered was exclusively that of the investigation of crime and the criminal. But since the state has “lost its innocence”, and since we have realized that the idea and the practice of law can differ very greatly, criminology has also addressed itself to the agents and activities of crime control.
