Occupy Wall Street: crowds march on NYPD, and the Radiohead concert that wasn't

Gawker's Adrian Chen is liveblogging the afternoon's events at the Occupy Wall Street protest in NYC. Sounds like some of the protest organizers (or an overenthusiastic supporter?) pranked the media about that "Radiohead concert," which is now revealed to have been a hoax—for the lulz? Or for more media attention? There are bigger crowds there now, at any rate. Along with the Wikileaks truck.
