7/7 Ripple Effect is a 57-minute homemade film produced and narrated under the pseudonym "Muad'Dib", who was later named by the BBC as conspiracy theorist John Hill. The film disputes the official account of the 7 July 2005 London bombings (also known as 7/7), a terrorist attack on public transport in Central London, by four suicide bombers later named as Hasib Hussain, Germaine Lindsay, Shehzad Tanweer and Mohammad Sidique Khan.
