> a deep pathological fear of the underclasses rising up
At least in New York, support for the police diminishes with income. Manhattan is the anti-police borough. The richest neighbourhoods within it elect the most anti-police politicians (with few exceptions).
I’m talking in the last decade. I was closely involved with Manhattan electoral politics 2014 to 2021. It’s not a coïncidence that the outer boroughs elected an ex cop.
No, it's not a coincidence but that doesn't mean its because of what you said. Go to the wealthiest parts of Manhattan and see if they don't want the cops.
