I was at that show (Score 2, Informative)

It is interesting to note that cameras weren't allowed in the venue. The tickets had a very distinct notice about that, and I personally witnessed at least one person who had to go back to the safety deposit booth to store her camera when the security guards found one in her bag entering the park. Of course there were thousands of cameras at the show, all of which must have been sneaked in. Seeing this great project and knowing the band's reputation, I assume it was the venue's idea to ban cameras. Maybe next time Radiohead will make sure this won't happen.
