Lilo,
Why do you think that conservatives are racist?
I don't think we'll see more "eruptions" like this. Only reason it's such a big story is because white on black crime is not nearly as common as black on white crime. Whites are held to a higher standard by the media and society and when they "erupt" it's more interesting to read about.
I don't know anything about this Derbyshire guy but, nowadays, even saying the above - no matter how true it may be - gets you labeled as a racist or a bigot. Liberals figured out a long time ago that that accusing conservatives of being racist, hateful bigots wins half the battle immediately for them. So they're very quick to play that card, again, no matter how true it may be.
