More the product of economic disparity than the influence of racists like the Black Panther Party or Black Hebrew Israelites.
Why stop at the highest ratio? Look at the second one. Again, I'd wager more the product of economic disparity and/or the influence of drugs and gangs than Latin power movements.
Why is it that whenever a racist white guy kills black people, there's almost the immediate response of, well they're killing each other to a greater degree anyway? It's rarely if ever, we've got a problem with racism and we've got a problem with crime, to which I'd agree. Bizarre, and as I aluded to, I think it betrays people's true feelings. And not to say there aren't plenty of instances where a black person kills a white one for plainly racist reasons. The difference being the weight of history, that is to say hundreds of years of slavery followed by another hundred odd years of collective disenfranchisement, discrimination, and humiliation points in one direction. Reparations won't fix it, but we're at a point right now where if you so much as point out, "Yeah the United States has treated black people like shit, and to a lesser extent we still do," you're going to get foaming at the mouth from one party and mindless self-hating adoration from the other.
I'll touch on another point. Take the uptick in black on Asian crime in New York (and I imagine every other major urban center). Deplorable, fueled by racism, cited by some on the right as an example of liberal hypocrisy. I agree with that assessment. The same people who bring up the point, though, are curiously silent when the President of the United States refers to the Covid as the, "China virus." Tack on Growl's favorite Robert F. Kennedy Jr. claiming that coronavirus was engineered to avoid Asians and Jews, everyone's favorite whipping boy.
