I absolutely agree with everything you said with one exception.

> "Protect and Serve"

Everyone thinks that the police's job is their motto. It was some strategic messaging, but they came up with that. Police weren't created to protect and serve. Going back to the foundations of the country's policing strategy, police exist to maintain order. That's why they arrest protesters, shoot unarmed guys who are noncompliant, arrest people for selling cigarette singles. That subtle shift in how we perseve their job explains vertically all of their behavior as of late.
