Scott Cummings uses terms like "black invasion" to describe demographic changes in the neighborhood. It's difficult to separate his obvious biases from his work, leaving a slanted product unfit as an accurate record. Lukas is a much more reliable narrator, however, and Common Ground is an excellent work.

Your statistics are uninteresting; the largest demographic is indeed the primary recipient of inter-demographic action from the second-largest demographic. This is to be expected in any interaction across any demographic boundary. Trying to use to it to advance some agenda is disingenuous, especially since 80% of all white people murdered are murdered by white people -- in other words, you're dealing with marginalia here.

The claim about the "lack of media attention" for black-on-asian violence is similarly absurd, since there is plentiful media coverage of the problem as a whole and your provided example in specific, as demonstrated in the sources cited by your Wikipedia link.
