Foucault State Control

This quote was under number three "the state- control of the mechanisms of discipline. Foucault began by saying the previous ways that the state has had a control over discipline throughout history as he talked about the religious groups of England that used to carry out social discipline and how they have now been taken over by the police apparatus. He talked about the police as being "the most direct expression of royal absolutism… "(Foucault 213) Foucault is discussing the state's relationship to the police. I noticed this was a reoccurring theme, but I was having difficulty figuring out what exactly he was trying to indicate the relationship. I then broke down the quote and translated so to attempt to understand it better.
"But, although the police as an institution were certainly organized in the form of a state apparatus, and although this was certainly linked directly to the centre of political sovereignty, the type of power that it exercises, the mechanisms it operates and the elements to which it applies them are specific."

In short, I believe that this means that police are directly tied to the values and ideas of the state' however, they are only implemented in certain situations.
"It is an apparatus that must be coextensive with the entire social body and not only by the extreme limits that it embraces, but by the minuteness of the details it is concerned
