OK, so I finally gave in and watched a bunch of "9/11 Truth Movement" (aka "9/11 conspiracy theory") documentaries. Some of these are very well made, a testament to the way digital technology has put high quality professional film-making within reach of almost anyone (see also Jonathan Caouette's Tarnation, for a very different example), which is very exciting indeed.
The films I watched are: Loose Change:Final Cut (2007) by Korey Rowe, The Great Conspiracy: The 9/11 News Special You Never Saw (2004) by Barrie Zwicker and Zeitgeist – the Movie (2007) by Peter Joseph.
However, I also felt obligated to watch a counter-documentary, the History Channel's 9/11 Conspiracies: True or False?
and also to read a bunch of online material debunking the Truth Movement's theories: Popular Mechanics magazine's special report, Debunking 9/11, etc. Of course, I also read a fair bit of online Truth Movement stuff, of which there's an astonishing amount.
So my conclusion? It's a work in progress, but for now I have to say I'm thoroughly unconvinced by the Truth Movement's arguments. It seems to me they're right that the US government is corrupt and wicked and lies through its teeth and has certainly carried out false flag terrorism in the past; and even that the US government is to some degree morally responsible for what happened that day. But did they actually carry it out? No.
Very interesting article here, though, from the Seattle Stranger, which looks at the place of the 9/11 Truth Movement in the broader political landscape. Particularly chuckled over this opening line:
The eight of them huddled around a table at a coffee shop could easily be confused for a comic-book fan society, or a Dungeons & Dragons kaffeeklatsch.
Ahem – he could be describing me…!
