The common shortcoming of all available investigations of the category of interaction called „Interrogating accused persons by the police“ results from the failure, quite common in criminology, to examine structural aspects on the micro-sociological level. Thus the internal dynamics of interrogation are obscure and, hence, so is the structural motivation imposed on the policeman. As a consequence of this analytical deficit, critical examination of the interrogating behaviour of the police has been limited to evaluation in terms of norm. In this essay the author endeavors to create a structural basis for understanding the interrogating behaviour of the police. His thesis: Not the policeman, but the interrogating accused person is the dominant in police interrogation.
