The photo shows a demonstration by members and supporters of the Ad Hoc Committee to End Discrimination. The demonstrators are staging a sit-in which blocks the entry/exit of the Oakland Tribune delivery trucks at the Oakland Tribune loading dock. The protesters are sitting crossed-legged in front of a chain link fence at the entrance to the loading dock. Also stationed along this fence are two police officers, who are standing among the protesters. The police are preparing to arrest and remove the demonstrators. A group of policemen in helmets is standing in the street facing the demonstrators, and a paddy wagon has been positioned in the street in front of the demonstrators. In the center of the photo is a man (reporter? Tribune employee?) dressed in a sports coat. He is wearing dark sunglasses and is carrying a briefcase. He is talking to one of the police officers, and may be holding a microphone(?). On the other side of the fence, a group of men has gathered (Oakland Tribune employees/delivery drivers?) and they are observing the protesters, police, and reporters. Behind these men an Oakland Tribune delivery truck can be seen - unable to leave because of the protesters' blockade. In 1964 the Ad Hoc Committee to End Discrimination organized a number of demonstrations to protest racial discrimination in hiring practices, including protests against Sheraton-Palace, Auto Row, Mel's Drive-in, and the Oakland Tribune. The Ad Hoc Committee picketed The Tribune building after William F. Knowland, editor and general manager of The Tribune, rejected hiring demands of the Ad Hoc Committee. The Ad Hoc Committee charged that the percentage of minority racial group employment was inadequate, and demanded that minority racial group employment on The Tribune be increased to between 15 and 20 percent of the total employment by December 15, 1964.
