adj : of or relating to a group of civilians organized to function like (or in aid of) a military unit n : a group of civilians organized in a military fashion (especially to operate in place of or to assist regular army troops) [syn: paramilitary organization]
Police departments are organized in a military fashion.
I don't know where you live, but where I live, the police don't go around attacking other communities and repealing attacks from other cities. So no, the police are not organized in a military fashion, other than some of the titles.
