John Hill made a film documentary about the 7/7 bombings. He used the nickname ‘Muad Dib’, taken from Dune and meaning ‘teacher’. The BBC has the story.

The official version says four British Muslims blew themselves up in the UK’s first suicide attacks, murdering 52 people and injuring 784 others.

But it took nearly a year for the official account to be published, and much of the evidence, such as CCTV and photographs, only came out slowly afterwards.

In that atmosphere conspiracy theories have flourished. A host of internet films now claim the government account is a deception.

If the official account is published too quickly, it’s obviously made up. If it takes too long, it’s obviously made up. Not an easy game to win.
