Now that Part One of The Path to 9/11 has been shown, it’s important to understand that this movie is based largely on the excellent work of FBI agent John O’Neil who perished in the attack.

PBS Frontline has an online special “The Man who Knew“, which you can watch online as well as other information about John and his work and just how close (if people would have listened) he was to stopping 9/11.

Give it a look.

UPDATE: Also Byron York’s 2001 article on Clinton failures to act on terrorism.
