This, patently, is ridiculous.
This, aspirationally, is reasonable. All cops are bastards, even the ones who are not white.
Part of making this practically reasonable would involve deprogramming white supremecist thinking from white cops. White supremecism and racism isn't people in white hoods and lynchings and the n-word. Those are symptoms, but not causes. Systemic racism, systemic white supremacy, is baked into the way the United States is structured. It is nearly invisible, and is meant to be totally invisible to white people. If you don't have to engage your sympathy because you don't know about it, you won't work from the inside to tear it down.
White cops are a symptom of all cops. All cops, though, are a tool of systemic white supremacy... any work to dismantle racism in America has to start with the mental and moral fortitude to dismantle the tools of white supremacy, and that means tearing down the cops to build up something community oriented and supportive instead. Cops protect property; they don't serve people. This should be the other way around. If we have more systems that serve people, and keep them from desperation, if we have systems that push towards wealth equality and mutual support, crime will go down and disorder will go down. But once you've got yours, you are less likely to share, so tearing down the systems means taking toys away from a lot of people who just happen to have a lot of the power.
It's a struggle, and no single effort will finish the work until the last effort does. Revolution is a series of failures that hopefully more the bar a little closer to equality for all. Progress has to be made in small steps, and victories seen not as the total implementation of the dream, but of making the life of people a little better each time, in ways that *actually* benefit people.
