Municipal/county/state police are not "militarizing" in any sense. There is no provision to "federalize" them like the state national guard. Even under the Patriot Act or other legislation. In the practical sense, the infra-structure and logistical problems alone prevent it for now. Hell the DoD refuse to even give their civilian cops ANY statutory arrest authority at all, and MP's are restricted by posse comitatus
Has a significant pile of Homeland Security grant $$$ been thrown at the states in the last decade? Absolutely. Is that indictative of our civilian police forces being molded into a single par-military entity...Ah NO!!!!!!!
