Zimmerman Riot? Against Whom?

Nationally, there are people threatening to riot if George Zimmerman is found not guilty of murdering Trayvon Martin.  Yeah, that's one way to obtain justice.... And land yourself in jail for longer than Zimmerman will serve. 

Aside from that, though, who will the rioters target?  George Zimmerman is half Hispanic and half white. So, will either race be the target? Both races?  Courthouses nationwide? Stores that sell firearms? (Wouldn't THAT be ironic?)

Will they all descend upon Sanford, Florida and riot there; or will they let their anger over the case cause them to harm their neighbors who've done nothing to them? If the people surrounding Sanford threatened to riot, I think it could be somewhat understood, but someone saying they're going to riot in New Jersey doesn't make sense.

Am I alone in my thinking?
