I think in today's climate, in the United States due to slavery and the civil war, and consequently the race problems we've had since the beginning and through to today, any time a white person kills a black person, it's going to make national news and it's going to be a big deal. Not saying I agree with it, because I don't, I think people have too much time on their hands and none of us were there, we're just siding along ideological lines.
All of this just shows how terrible race relations in the United States still are. There aren't really any modern equivalencies to it, either. We're sort of a special case, so it's difficult to point to any other modern society and say "Look, they had similar problems and they're dealing it much better than we are." It's impossible.
We're sort of still in the experimental stages of our American society, and we're learning things as we go, and this kind of thing isn't going to go away anytime soon. We still have African-americans calling for reparations for crying out loud. Today. People that are no less than eight or nine generations removed from slavery.
