At the risk of pontificating, it is very sad that after more than a hundred years of dismantling racial barriers we have, as a society, seen over the last twenty years parts of society - professional "community leaders" and Gubermint types being the most guilty - putting the barriers back up.
The whole gang culture thing is of course the most odious aspect of this, especially given that it escapes any kind of social stigma (indeed, often its the exact opposite), and is promoted as a lifestyle choice - or at least accepted as a way of life - by people who really should know better (in addition to those stuck in the middle of it).
edit: oh, and its not particularly of relevance but she is very pretty.
