This may be the single greatest web site I've every stumbled across. It's the FBI's
Freedom of Information Act Reading Room. In it you'll find (edited, yes) dosiers of thousands of Americans that the FBI trailed over its history. So far I've looked through Andy Warhol, Frank Sinatra, Tupac Sakur, and Cardinal Spellman. Check out Michael Spilotro's file. He's the guy that Joe Pesci played in Casino, the one who gets wacked with his brother in a field in Indiana. It's a guilty pleasure I admit.
