One of the protest leaders, Boots Riley, touted the day as a success, saying “we put together an ideological principle that the mainstream media wouldn’t talk about two months ago.”

His comments came before a group of demonstrators moved to break into the Travelers Aid building in order to, as some shouting protesters put it, “reclaim the building for the people.”

Riley, whose anti-capitalist views are well-documented, considered the port shut down particularly significant for organizers who targeted it in an effort to stop the “flow of capital.” The port sends goods primarily to Asia, including wine as well as rice, fruits and nuts, and handles imported electronics, apparel and manufacturing equipment, mostly from Asia, as well as cars and parts from Toyota, Honda, Nissan and Hyundai. An accounting of the financial toll from the shutdown was not immediately available.

The potential for the chaos that ultimately erupted was not something Riley wanted to even consider.

“If they do that after all this …” He paused, then added, “They’re smarter than that.”

But the peace that abided throughout the day, did not last into the night.
