In the last 10 years, in narcotics task forces, in a number of violent crime task forces, we've worked very closely together with state and local law enforcement.

In the context of September 11, there were so many that lost their lives that - how do you single out one person? There were so many acts of heroism that day from so many people, whether it be firemen and police officers in New York and our agents also.

What we bring to the table is not only our 56 field offices in the United States and our number of resident agencies, but also we have 45 legal attaches overseas.

People talk about the Patriot Act that was passed immediately in the wake of September 11. What the Patriot Act did was break down the walls between the various agencies.

In the United States, it's the mandate of the FBI to gather information relating to terrorism, go out and collect it, to do the interviews, to do the investigative work.

Prior to the passage of the Patriot Act, it was very difficult - often impossible - for us to share information with the Central Intelligence Agency, with NSA, with the other intelligence agencies, and likewise, for them to share information with us.

And from the moment that we realized it was a terrorist attack, there isn't an agent or a support person in the FBI that wasn't committed to bringing to justice those who were responsible for this.
