“Liberty” under capitalism is freedom to exploit and hold private property. The police, as an instrument of class rule defend businesses (who probably have insurance anyway) from “rioters” who are simply expressing anger at the unjust killing by police. The people that are killed by police are almost always poor, having no property to compel the state to protect them. We can compare over a thousand dead at the hands of US police a year to only nineteen in the history of the People’s Republic of China. Which one is more “authoritarian?”
