Do you specialize in hearsay? "I heard that some dude, over behind the trash bin, I think it was behind the supermarket, and he said that no nukes is a convicted grave robber."
See how that works? If you make a claim you MUST back it up with evidence greater than that which you pull out of your keester.
It was on the front page of the London Times, which is a Rupert Murdoch newspaper. A few weeks later there was a follow up article. It was somehow ignored by the US media, which my wife and I found very strange. An American relative told me that she heard the story, and that it was in the 9/11 Commission Report.
You are talking about Niaz Khan. His story is in the 9/11 Commission Report and was reported as major news in Great Britain. He is a citizen of Great Britain. The FBI confirmed some of his allegations. He did not know any of the 9/11 terrorist or anything about the 9/11 attack. He claimed he was trained to hijack an airplane in but never given specific details. After his training he was sent to New York to allegedly meet with an al Qaeda representative for further instructions. He claims that instead of joining the assumed secret al Qaeda cell that he fled with the funds provided to him by al Qaeda and after blowing the money on gambling (he was a degenerate gambler) he went to the FBI in fear that al Qaeda was coming after him for stealing their funds. This was in 2000. The FBI sent him back to GB and British intelligence. British released him. His story can be found with a simple name search on google.
When asked why they did not investigate his story, an FBI spokesperson said that they began an investigation, but were told to stand down by someone higher up in the government.
