] San Francisco -- A survey using sophisticated aerial
] photography of Sunday's anti-war march and rally in San
] Francisco has produced results that indicate a far
] smaller crowd than the 200,000 protesters estimated by
] police and event organizers. ]
] The results of the independent survey, commissioned by
] The Chronicle and SFGate.com, cast doubt on traditional
] counting methods and contradict the crowd estimate of
] 200,000, which was reported in this newspaper and news
] media around the world. Crowd size in a demonstration is
] important because organizers tend to use it as evidence
] of support for their cause.
