If you want to fan the flames, though, add a section for protesters savagely kicking unconscious victims in the head.
As a society we give police a monopoly on civilian violence, it is only reasonable to expect the holders of that power to be held to the highest possible standards.
But the justice system signals the exact opposite, by systematially protecting even the worst cops from the consequences of their actions. This, I believe, lies at the core of the people's rage. I for one think that rage is justified.
