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

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.

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

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