I get the impression there are quite a few people here who have a serious, sustained concern about 9/11, the aftermath, and the Saudi involvement. In which case, this will really interest you.
The Saudi Connection: Inside the 9/11 Case That Divided the F.B.I.

But others who worked on the matter, including some at the F.B.I.’s highest levels, say that the United States’ complex and often-troubled relationship with the Saudi regime was an unavoidable fact throughout their investigations. Even as the Saudi authorities became more cooperative with the United States in fighting Al Qaeda after 2003, they were minimally and grudgingly helpful when it came to the 9/11 inquiry.
