Good question! Would you care to contribute a paragraph to add to Freeper Lore?
Michael Rivero -- FreeRepublic's resident conspiracy theorist / expert. Rivero presented voluminous evidence on several theories, including TWA flight 800, which Rivero maintained was a friendly fire accident, covered up to insure a smooth campaign season that year. However, Rivero (like many other conspiracy buffs -- go figure) tended to find conspiracies where there were none -- that is, there is no such thing as an accident, anywhere. For a while most any report of a plane crash would result in Rivero being jokingly pinged to uncover the "real" causes. Rivero even formulated a theory or claim that the JFK Jr plane crash was a "hit," rather than pilot error. Rivero was banned, when, following 9/11, he began to claim the American government / Bush / etc. had orchestrated or somehow condoned the attack on the World Trade Center.
