Forensic science
What Foucault reveals is that the original police had a different function as we know it today; for example one of their primary function was to administer the state in the guise of statisticians, allocating resources, supervision of grain in times of crisis, ensuring circulation of goods and men, secure the development of the state's forces. This was so successful this then led to an extension of the franchising out in the form of recruitment of the then University system. This bought in the next generation of administrators for the new ‘nation state’ system. This bought in two types of police; administrators who formed the Polizeiwissenschaft; the science of police or the science of government of the state, the other type would become known as what we know and associate the term today criminal justice system, Law enforcement, Forensic science and the modern uniformed police Polizeistaat police state, translated into English as policing of the state.
