On the West Side it can be Asian gangs as well. Certainly were for some of the drive-by shootings in Houston's history. It is where the "new China town" was established (although it is comprised of Chinese, Vietnamese, Koreans, and Indians).
I know people are gonna bash me for referencing him, but in his new book, Buchanan shows figures that Asians, while they are less likely to get arrested than whites, are something like four times more likely to join gangs.
Hispanics and blacks, on the other hand, are much more likely to join gangs and get arrested.
