    How Sept. 11 reshaped national security

    It’s been 25 years since al-Qaida attacked the United States by hijacking airplanes and crashing them into the World Trade Center and the Pentagon, with a fourth plane crashing into a field in Pennsylvania. Sept. 11 represented a new kind of national security threat, and a new national security architecture was created to confront it. Before a live audience at NPR, host Mary Louise Kelly discussed how that day changed the country and its spy agencies, with people who worked on the frontlines of government and intelligence.
