> I wonder why the police are given so much more weapon's autonomy than the military?

I think because there is no political will to protect the usual victims of police brutality—indeed, the "tough on crime", and concommitant "tough on people who are in the general vicinity of people perceived to be criminals", mentality, is perenially politically popular.

Of course there is also no political will to protect the usual victims of military brutality, but they can and do (in many cases, to some extent, at least historically) protect themselves, and so it has been perceived that it's necessary to reckon with the possibility of reprisal.
