Thousands of Occupy protesters who forced some ports on the West Coast to halt their operations Monday vowed to stay through the night. Demonstrators flooded into shipping terminals in California, Oregon, and Washington state, despite attempts by police to bring them back to designated protesting areas. Occupy Oakland effectively shut down operations at two shipping terminals, including one operated by Goldman Sachs, when unions sent about 150 union workers home. "The Occupy movement is attacking the 1 percent at their point of profit," said Mike King, a media liaison for Occupy Oakland. Port of Oakland communications manager Robert Bernardo said protest only hurts workers. "It's important to keep the Port open so that workers can make a living," he said.
