This particular pathology makes more sense when you recall the traitor statues of Robert E Lee, etc; there's a substantial faction in the US which is against the US specifically because it won the civil war and imposed the end of slavery on them, which they remained upset about into the 20th century and schools in Alabama being integrated at gunpoint.

That's why the "anti-government" faction doesn't care about civilians being unjustly shot dead by police, because they're not federal government.
