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.
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.
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.
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.
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.
