The San Francisco Chronicle reports an aerial survey of this weekend´s anti-war protest shows the number of attendees was around 65,000 people. Police and organizers of the San Francisco protest originally estimated the crowds at about 200,000. Alex Jones is a media scholar at Harvard University. He says crowd estimates are usually mythical numbers and turning them into facts won´t be welcomed. Police and organizers say they stand by their crowd numbers.
To get the estimates photographs were taken from two-thousand feet. A grid was placed on the pictures and each grid was evaluated and assigned a density of people from ten to 100 percent full.Most areas of the grid were judged to be 25 to 50 percent full.
