Journalism professor Robert Scheer recently wrote a Sept. 8 article for Truthdig questioning the extent of public knowledge on the origins of the 9/11 attacks.  In "How Little we Know about the Origins of 9/11," Sheer wrote that "it is not conspiratorial but rather obviously plausible" to suggest that the causes for the 9/11 attacks have been intentionally hidden from the American public. Scheer wrote that the scheduled public, civilian trial of the alleged 9/11 mastermind Khalid Sheikh Mohammed was called off by the Obama administration because of "hysterical Republican-led pressure." "Surely a public trial would have revealed, to the deep embarrassment of the Bush administration, that there was no connection between the 9/11 hijackers and the government of Iraq that the United States overthrew," Scheer wrote.
