I think they could still throw a pretty good riot if the wanted to:

That is one of the points east where they left too. BTW, Victorville is a relatively small town, far from LA, out in the desert. Many left to the inland empire of s. CA, but most kept going east, south, etc.

LOS ANGELES--A decade ago it was odd to see young (and not-so-young whites) walking their dogs, jogging and attending community meetings around my neighborhood in the western section of South Los Angeles. That’s not the case anymore.

Young and not-so-young whites are now a fixture in the neighborhood—and in many others. The black population of Los Angeles has shrunk from nearly 20 percent of the city’s overall population in 1970 to less than 10 percent today.

The population shift has happened in parts of every major city from Oakland to Washington, D.C., including cities that at one time were either exclusively or predominantly black. The latest U.S. Census figures more than confirm that America’s urban racial and ethnic demographics are fast changing.
