Yemen Hub - Sumamry of 9/11 Timeline Chapter

I wrote a summary of the Yemen Hub chapter in the 9/11 Timeline. It is about the NSA listening to the hijackers' calls and how their explanation for why they didn't catch the hijackers based on the intercepts doesn't make any sense.

It begins:

Yemen Hub: NSA was listening in on the 9/11 hijackers’ calls for years

And how this became the rationale for the NSA’s warrantless wiretapping program

The “Yemen hub” was an al-Qaeda communications hub that fell under US surveillance in the mid-late 1990s and was also home to Khalid Almihdhar, said to have been on the plane that hit the Pentagon on 9/11. There are still many unanswered questions about the surveillance, such as why were the NSA and its fellow agencies unable to roll up the plot based on the intercepts? And how did it come to be used as the justification for the NSA’s current domestic warrantless program?
