Someone posted on FR yesterday that many of the organized flash mobs, such as the one robbing the Topanga Nordstrom in Los Angeles, were recently arrived African and Haitian gangs. This Freeper was supposedly told this by a cop friend who had inside info.
I'm sure there's some of them doing that, no doubt.
I don't have the statistics. I doubt anyone is doing that in California.
But it appears to me that it is mostly American Blacks in California that are behind all the robberies.
