In August 2002 , in the run-up to the 2003 Iraq War , Kollerstrom became a founding member of the Legal Inquiry Steering Group , a citizens ' tribunal in the UK that challenged the legality of the war . In 2006 he appeared in a video by David Shayler , supporting a fringe conspiracy theory that the men accused of the 7 July 2005 London bombings had not carried out the attack . According to the BBC , Kollerstrom found that the Luton – London train on which the bombers were at first said to have travelled had been cancelled , which led the government to correct the official account of the men 's movements . The police said the correction had come from them . Kollerstrom 's book '' Terror on the Tube : Behind the Veil of 7/7 , An Investigation '' was published in 2009 , and he was interviewed that year for the BBC series '' The Conspiracy Files ''
