There are poor Asians, Hispanics and whites but we don't see them burning down cities and making complete fools of themselves.
In general, you are correct. However, in the Los Angeles Rodney King riot, Hispanics were highly joined in after a few days. They were at least half of the rioters that attacked Parker Center (LA Police HQ's) one night. I witnessed it on TV and subsequent photos. They were also starting to roam the streets and causing problems in East Los Angeles.
Granted, most were probably illegal aliens and gang members. But they were there. I watched the entire event from ground zero. Kinda tough to try to ignore it since it went on for days and destroyed much of central Los Angeles.
The heroes of the debacle; the Korean store owners on top their roofs with guns pointed down. I've asked before if ANY of those Korean stores were looted and/or burned, which I don't recall any were. If I'm wrong, please correct me.
