"I understand the Saudis have been named because fifteen of the nineteen hijackers were from Saudi Arabia"

This quote by Sibel Edmonds suggests that the Saudi Arabian federal government may have had some involvement in the 9/11 terrorist attacks. The truth that fifteen of the nineteen hijackers were from Saudi Arabia implies that the Saudi government might have had some understanding of the attacks or perhaps been complicit in them. This could explain why the Saudis have been called in connection with the attacks. It is possible that the Saudi government had some participation in the planning or financing of the attacks, or that they had anticipation of the attacks and failed to act. Whatever the case might be, this quote suggests that the Saudi government might have had some participation in the 9/11 attacks.
