From this article:

Oakland police opened fire with sand bags and rubber bullets on a group of longshoreman at the Oakland docks as protesters marched in front of the AP-L pier to protest the war in Iraq.



The longshoremen were standing on the side of the road and were not involved in the protest. Six were being treated by paramedics and at least one was transported to a hospital.

Police also were using tear gas and concussion grenades to disperse the protesters.

Some 300 anti-war protesters were at the entrance to the AP-L pier, barring the way. At one point -- some 15 trucks carrying huge containers were waiting outside the gates for police to clear the way for them to enter.

About 100 activists were protesting at the Federal Building in San Francisco and about 30 were at the Concord Naval Weapons Station.

The protests come two weeks after demonstrations sparked hundreds of arrests and brought downtown San Francisco to a standstill.

Most of the Concord Naval Weapons Station is closed. But protest organizers say trucks have been seen transporting material out of the facility since the war began.

During the Cold War, the weapons station was the scene of frequent protests. In 1987 protester Brian Willson lost both legs after he lay down on the tracks and was run over by a train.
