I imagine - from the NYPD POV - there is already a war between the people AGAINST the cops. Between the "I can't breathe" protesters on the left and "Cops are scum" libertarians on the right; I imagine the cops really do feel alone and set apart by the people.
I object. I am a Libertarian. We recognise national defense, civic police and a good court system as basic to the Constitution. The real job of government.
I make a point of thanking officers for their service, buy them a donut once in a while
