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 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.

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.

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.

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.

In planning an attack, persons have various roles.

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.
