There’ll be differences of opinion in just about every intelligence analysis that you make.

The FBI’s principal priority right now is protecting the United States against another terrorist attack.

All I’m going to tell you is investigations, whether it be this and others, where you have partial facts, analysts, agents are always trying to interpret what those facts mean, extrapolate from them what they mean.

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.

The collapse of Enron was devastating to tens of thousands of people and shook the public’s confidence in corporate America.

Secondly, not only have we put additional agents on counterterrorism, but we’ve also built up our analytical structure so that we’re better positioned to analyze the information we have.

And so every one of us in the FBI, I don’t care if it’s a file clerk someplace or an agent there or a computer specialist, understands that our main mission is to protect the public from another September 11, another terrorist attack.

We cannot go up on a wire. We cannot do a search without a judge on the FISA Court approving it and determining that we have met the standard that has been set forth by Congress in order to utilize these techniques.

They’re – FBI agents are some of the finest people you’ll find anyplace in the country or the world. And I’m lucky to have the opportunity to work with them.

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.

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.

In order to be successful against each of these threats, we have to have a presence overseas, work closely not only with our counterparts in the law enforcement community, but also with the intelligence community.

I would say in just about every investigation we have, there will be differences of opinion, where you have partial facts, as to what those facts mean.

I know when I was here prosecuting homicides in the District of Columbia, one of the most effective units here was the cold case squad, which had on it FBI agents, as well as Metropolitan Police Department homicide detectives working together.

I was in my office when – on 9/11. I think I had a number of meetings scheduled. I was just getting to know the bureau. And somebody walked in and said the first plane had – or a plane had struck the World Trade Center, one of the towers.

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.

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.

The 19 hijackers that came over here to commit the attack on Sept. 11, there were those that were at the bottom of the line. There were those who were the principal conspirators. There were those who were the pilot. Everybody has a role.

Leaking of classified material is a concern.

But we had – I think if you look at law enforcement 10 years ago, if you look at the challenges, the FBI was focused excessively on what was happening in the United States.

So there is a foreign intelligence purpose for every one of our FISA warrants.

And at that point, I think we all realized it was something tremendously tragic, probably a terrorist attack, and the next step was to go down to our command center and get things going.

So without getting into the specifics, I can tell you that to the extent that investigation is a relatively important investigation and meaningful, the president would have been periodically briefed.

It’s because we need to determine who in this country is poised, positioned to commit terrorist acts.

We had to address information technology in the ways we had not before and give the agents the tools that they need to do their job more efficiently and more expeditiously.

I didn’t know the organization, but the one thing you can say about the FBI, it’s tremendously professional.

I think around the world, our agents are the best collectors of information you’ll find.

As I said before, there are often disagreements as to what a particular set of facts mean. That is not at all unusual, and one shouldn’t read into it more than is there.

There’ll be differences of opinion in just about every intelligence analysis that you make.

I asked a Burmese why women, after centuries of following their men, now walk ahead. He said there were many unexploded land mines since the war.

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.

If you look at the 19 hijackers who came to the United States in Sept. 11 to commit those acts, if you’d looked at them before they got onto a plane, you could probably say the same thing. There were various levels of expertise, various levels of competence.

In planning an attack, persons have various roles.

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.

But since September 11, we have made every effort to try to work closely with state and local law enforcement.
