I think there's an interesting phenomenon where even white normies understand how demonically racist the American institutions are. Ideologically committed racists don't, but everyone else sees at least part of it. However, because this only gives you a negative assertion (don't trust what the courts say) and the isn't really a normative, absolute system we can trust in the absence of any reliable rulings from the hegemonic institutions, we're just left with a wide space of viable interpretations of reality, which lets people get off the hook for assuming reality must be close-ish to what said racist institutions uphold. That closeness between imagined reality and the reality white supremacy wishes to impose is what allows for people who aren't ideologically committed racists to passively accept the brutalization and murder of marginalized people. "Oh, I can't support those cruel acts, but the sad reality is they probably didn't happen for no reason either" is the refrain of the embarrassed white moderate.
