Deep Throat, again:
Bill Gaines' investigative reporting class at University of Illinois, after a 4-year investigation, announces their finding: Fred Fielding was Deep Throat.
A credible choice, and very well presented. Worth a read. Check the gallery, media section for reaction from newspaper editors (and Carl Bernstein, who went ballistic on them), and archive of other Deep Throat revelations, too. (Thanks to Gary Price for the heads up in NewsLib.)
