I state both the original claim and the retraction in the paper. However, he did not retract his position on the tube stations - he only retracted claims about the size of the mock terrorism exercise. I'm not sure which "three claims" you are referring to - I can see no claim in my paper that is not fully validated by the reliable evidence that people have subsequently provided to this thread (i.e. Peter Power's own words).
a) Peter Power claimed the stations were the same in his exercise as the official version of the bombings. Peter Power himself confirms this.
b) Peter Power originally stated that the mock exercise involved a company of 1,000 people, and later stated that it involved only 6 people. This is the extent of his retraction - duly noted in the paper I wrote.
c) That Peter Power may be a dupe, not an accomplice .... this accepts that someone else may have used knowledge of his mock exercise to hide their own activities. This is duly noted in the paper as well.
For the avoidance of doubt, here is the quote from the paper.
"7/7 Ripple Effect, by rejecting the thesis put forward in the BBC documentary that the men exploded bombs and died, has to account for what happened to the four men during the remainder of the day. It puts forward an argument that the men were recruited to an event organised by Peter Power, a former PR officer for the Metropolitan Police, who simulates terrorist attacks for clients to practice their crisis management skills. The information in the following paragraphs is drawn from the documentaries, and multiple sources collected together at
http://julyseventh.co.uk/july-7-terror-rehearsal.html#cbc (accessed 3rd October 2009).
Both documentaries show Peter Power appearing on several TV programmes on the morning of 7th July 2005 claiming to have been running a crisis management simulation for a ‘client’ based on a scenario of four bombs going off in London at precisely the same locations and times. 7/7 Ripple Effect includes video footage of Peter Power’s involvement in an earlier BBC Panorama programme made during 2004, in which public figures examine how the media should cover a terrorist attack involving three tube trains and a truck in central London. There is, therefore, no dispute between the two documentary makers that Power was running a mock terrorism exercise in London on the same day, or that he specialised in terrorist crisis management techniques. The theoretical dispute centres on whether the Muslim men were bone fide bombers, or patsies recruited to participate in Peter Power’s simulation exercise to take the blame for the real bombings.
Power has admitted that he recruits people to make videos, including people who role play different parts in the simulated crisis, so that the simulations he runs are as realistic as possible (J7, 2008). The 7/7 Ripple Effect claims that it is plausible that the four Muslim men were part of Peter Power’s simulation, but offers nothing more than circumstantial evidence to support this view. Power is interviewed in the BBC documentary and rejects a claim that a 1,000 people were involved in a simulation that day. Instead, he claims that the simulation was a ‘run through’ with only six people in a control room. This retraction is problematic in light of eye-witness evidence from Daniel Obachike who saw people acting out their injuries and the provision of medical help near Tavistock Square after the bomb blast on 7th July (Jones, 2007). Within 15 seconds of the bomb blast, Obachike saw an actor covered with bandages, surrounded by cameras and helpers, being filmed as he was taken away from the scene. The person was filmed leaving before any ambulances or medical staff had arrived at Tavistock Square and images later appeared in press and TV reports. This suggests that the coverage was planned in advance. So, even if Peter Power did not hire people to participate in his ‘real life’ simulations, an eye-witness account confirms that a terrorist simulation involving many more than six people took place in London on 7th July 2005 (Obachike, 2007)."
This accurately summarises the information that is in the public domain.
