Police need to be militarized to do their job. They are in a war against various forms of crimes committed by civilians and as such have to approach US civilians like any other army would approach their enemy. It is also why police use the term "civilian" in a derogatory way along with various ethnic slurs when talking about the enemy they face as a way of dehumanizing them much like krauts, nips, slopes, gooks, dune coons, and similar terms have been applied to enemies on other battlefields.
"My message to my troops is if you see anybody carrying a gun on the streets of Milwaukee, we'll put them on the ground, take the gun away and then decide whether you have a right to carry it." - Milwaukee Police Chief Ed Flynn
