Farrakhan was widely criticized after he complained that the U.S. Park Police underestimated the size of the march. But he may have been closer to the truth. Citing an analysis by Boston University's Center for Remote Sensing, ABC's "Good Morning America" reported today that the figure is about 870,000, more than twice the official estimate of 400,000. A special digital analysis was used to evaluate Park Police photos in greater detail. The study has a 25 percentage-point margin of error, which would mean attendance could have been as low as 655,000 and as high as nearly 1.1 million.
