Actual-and-for-true Big Dumb Journalist attempt to refute photographic evidence:
However, CBS News wins the big prize here. In a web piece called Glenn Beck; “Something Beyond Imagination Is Happening,” the last-place news network actually reported their estimate for the crowd to be 87,000. Seriously. There has been no claim of website hacking by CBS, so one must assume that they meant what they wrote when stating; “Approximately 87,000 people attended the rally, according to a crowd estimate commissioned by CBS News. The estimate was made using aerial photos taken at noon, which was judged to be the height of the event. The estimate has a margin of error of 9,000 people.” CBS News is also the network setting records in the ratings department, the low ratings department.
It's not especially a secret that wingnuts don't like it when someone says something that doesn't flatter their grossly distorted self-perceptions, but this is still pretty ballsy. "Your pictures don't show 400,000-plus imaginary people, and that's why nobody likes you!"
