I was never quite sure if it was the Sauds, the Pakistani ISI, or both. That aspects of 9/11 were covered up was obvious to anyone who doesnt drink the MSM koolaid - more detail coming out.

There was another info drop a year or so ago, slowly but surely more pieces coming to light.

Been pretty sure all along that the Sauds at least knew more than we've been told.
