I must admit that I don't follow the conspiracy genre as well as I ought, but I think it's safe to say that David Icke plays in the big leagues. All of the major political figures are represented in his remarkably thorough understanding of the machinations of such as the Illuminati, the Rockefellers, the Masons... the usual suspects. This is all familiar territory, though well-represented; nothing spectacularly innovative (although I had not heard before that the Mormons and the Jehovah's Witnesses were really just two wings of the same organization, or that Jim Morrison was murdered to shut him up).

Icke's biggest scoop came from a meeting he held with a senior member of British Intelligence, who told him (in misplaced confidence as it turns out) that the British Royal Family are shape-shifting reptilians. When Diana found out (try not to think about how), she was murdered in the Pont de L'Alma tunnel at column 13, an ancient Illuminati sacrifical site.

Anyway; turns out these reptile people are really in charge, and the rest of the conspiracies are just departments of the Big Con. Now you know.

All in all: a great source of consipracy-themed rants. As fun as Robert Anton Wilson with a good editor.
