(AP) - The police protest epicenter in California shifts to Oakland Wednesday.
Organizers say they expect hundreds to come out and help shut down a federal building to show anger at the killing of unarmed black men by white police officers.
Protests continued in Berkeley last night where hundreds marched through downtown streets, briefly blocking traffic on a state highway, and delaying metro and train services.
Protesters stopped at City Hall, where a city councilman addressed the crowd and said he will ask for an investigation into police response to the protests.
Berkeley Mayor Tom Bates says a City Council meeting scheduled for Tuesday night was canceled after threats to disrupt it.
