If the London terrorist attacks of 7 July 2005 have not obsessed conspiracy theorists to the extent of the American 9/11 attacks, they have still been fertile ground. A summary of sorts is provided by Tom Secker at the Centre for Research on Globalization:
We are on the eve of the 7th anniversary of the 7/7 terrorist attacks in which 56 people, including the alleged culprits, were killed. In that time, numerous theories have been put forward as to what really happened and who was truly responsible. The official theory, that four young British Muslim men radicalised each other into a fanatic religious rage that they chose to express through the medium of suicide bombing, is perhaps the best known. It is, naturally, a conspiracy theory, though because it is officially sanctioned it does not tend to get given its true name. It claims that the four men conspired, with malice aforethought, to murder over 50 people.
Refuting the official conspiracy theory has been a painstaking process for those sections of the independent research community, but is has been a thoroughly successful one. 7/7 is, at its simplest, a horrible crime. In investigating that crime we can look at it in relatively conventional terms of means, motive and opportunity.
Exactly what means were used to kill the victims of 7/7 has never been established.
The official cause of death in each case is ‘injuries suffered in an explosion’, but the actual explosive used has never been determined. At the July 7th inquests into the deaths of the 52 (excluding the alleged bombers), explosives expert Clifford Todd admitted that they found no trace of the main explosive at any of the bomb sites.
This presents several potential scenarios. It is possible that the forensic examiners were utterly useless. The record of such scientists in this country is quite terrible. It is possible that the explosive used was exotic, unknown to the existence investigative science in this area. It is possible that they did figure out what explosive was used and it had nothing to do with the organic peroxide-black pepper/powdered Masala concoction supposedly used by the alleged bombers, and therefore they hushed it up. It is possible that the explosive used was of a very sophisticated kind that left little or no trace, consuming all the explosive substance in the chemical reaction.
In any case, since we don’t know the means that were used to kill those people, asserting that the alleged bombers had that means is absurd.
The supposed motive has never been formally established. No one who knew any of the alleged bombers suspected they would become mass murderers…
