About 150 people marched through downtown Oakland Saturday night protesting the acquittal of George Zimmerman for killing unarmed teenager Trayvon Martin last year in Florida.
Many marchers were peaceful, but some people smashed storefront windows and lit fires in the streets.
Protesters also set upon an empty BART police car near 12th and Broadway. Oakland police say they made no arrests.
More rallies are planned for Sunday afternoon in both Oakland and San Francisco.
