It's kind of interesting. If someone guesses "white" shooters, that okay --- no one calls them a racist. It's okay to speculate as long as you speculate Columbine type spoiled white kids. It's even okay to speculate white kids doing a drive-by shooting even though I'm not sure there have been any cases of that ever.
It's also pretty interesting no one speculated immigrants from India or any other kind of Asians might be the shooters. No one even speculated Arab Muslim kids doing a drive-by shooting.
Asian Boyz are pretty big in that area and the SGV. Ruthless little SOBs.
