Translating words into action

You may have already seen this story from Salon by Eric Boehlert on former FBI translator Sibel Edmonds. Edmonds testified to the 9/11 commission about her work translating terror-related tapes and documents from the pre-attack period. She reports that "there was specific information about use of airplanes, that an attack was on the way two or three months beforehand and that several people were already in the country by May of 2001."

Two simple questions:

1. Why didn't Bush tighten airport security?

2. Why has no-one from the press insisted that Bush answer question #1?
