Sibel Edmonds happened to be translating information from terrorist networks that confirmed plans to use aircraft as missles. Moreover, there were several attempts to gag her on this subject- she claims. She's been paraded before several committees, including the 9/11 Comission, Senate Judiciary Committee and the Senate Select Intelligence Committee.
What I personally want to hear and see is more corroboration of her testimony. I find it hard to believe that she was the only person to handle and translate that information- there must be other individuals that can confirm her claims.
