(Update) 3:50 p.m.: It looks like the madness is moving down Marker Street, where protesters are blocking traffic. So yeah, your commute home will suck. The Occupy Party bus has arrived, and is headed toward the Civic Center, it appears. Meanwhile, Wells Fargo is playing it smart and has boarded up all its windows, not that this demonstration has been anything like what we saw in Oakland.
(Update) 2:27 p.m. Sgt. Michael Andraychak tells us that as of 12:30 p.m., a total of 19 protesters were arrested after refusing to move away from the Wells Fargo exits. Police are still in the Financial District, but Andraychak says the demonstration seems to have calmed down for now. "It ebbs and flows," he said. SF Weekly's Browner tells us that protesters have gathered outside of the Bank of America on Montgomery, closing off the street off. Police are standing nearby in riot gear.
(Update) 1:16 p.m. Browner now tells us a group of peaceful protesters are moving to City Hall, singing bluegrass tunes of all things. Browner says she's seen a handful of protesters arrested, and confirmed with Occupy that at least seven demonstrators have been hauled to jail. However, other media outlets are reporting that number is now at 19. Police are no longer lingering at California and Kearney, but no word on where they are now.
Update: (12:23 p.m.): A police source tells SF Weekly that occupy protesters on Market Street are posing as undercover cops, arresting their fellow protesters. "
