Let me understand, please. You don't believe that US Government agencies held a part of 9.11. Other than it (government) didn't PREVENT a PREVENTABLE?
While I don't believe the government held a part in 9/11 other than not preventing something that could have been preventable I do believe that the government does withhold all of the truth on things. I think some of it is because of security reasons and things along those lines and some of it is because of them not wanting to reveal bad things they have done.
