After George Zimmerman was acquitted in the killing of unarmed teenager Trayvon Martin in Florida, several rallies sparked up shortly after the not-guilty verdict was read. In San Francisco, authorities temporarily shut down Valencia after hundreds of protesters marched in disgust, chanting "Justice for Trayvon Martin."

Peta Lindsay, a Party for Socialism and Liberation member who snapped the above shot during last night's protest, had this to say:

"When I heard the verdict, I cried. Then I asked myself- but what am I going to do? What do you do when the whole system is racist, when the cops, the court, the media tells you that your life and the life of any child that looks like you can be taken without consequence? Right away my comrades showed me the answer- you fight back. [...]"

A protest will be held today, Sunday, at Powell and Market at 4p.m. and is expected to draw an even larger crowd.

In Oakland, a little over a hundred gathered at Frank Ogawa Plaza near Oakland City Hall and marched downtown. According to The Chronicle, the group started small fires and smashed windows at the Wells Fargo Bank at 12th Street and Broadway and at several locations, "including the Dogwood Bar, the Oakland Tribune, the Foot Locker shoe store and the Sears store."
