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.

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.

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

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.

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.

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