“The police cannot be reformed—more than a century of experience proves this beyond a reasonable doubt. Even if we tried, and we do continue to try, police resist tooth and nail even the smallest reforms and the most minimal accountability.

As we have seen, the history of American police is the history of their expanding power, and it is a voracious power that accepts no limits: a fascist power.”
