It's been a good week for conspiracies, what with Peter Davis joining the Exclusive Brethren and Don Brash finally coming out as a socialist.

The week started with the SST, my future employer, spending about 12 seconds to find out what Investigate didn't.

The same day, I walked into a shop and the guy had a copy of the 9/11 conspiracy DVD Loose Change ready to watch as soon as the doors closed.

Loose Change is a compelling little video - available for free from its makers - that doubts that planes hit the towers and the Pentagon etc. But that would involve fooling the President ... Ah, hey, if it's good enough for former MI5 agent David Shayler, it's good enough for just about any old ex-spook.

The day before, I finally got off my arse and went to see the really quite good Saint of 9/11 at DOCNZ, a, yes, hagiography of a gay "recovering alcoholic" priest; he was the chaplain of the NY Fire Department who died on 9/11, so the film wrapped the Ground Zero hero around his other "issues". Nice bloke, really.

Then later in the week, George Monbiot reckoned there's a Big Tobacco link to climate change denial. My head was spinning.

What's a sceptic to believe?
