I knew from the beginning that privacy was going to be a huge issue, especially with regard to applying Total Information Awareness in counterterrorism. Because if the technology development was successful, a logical place to apply it was inside the United States.

Nobody - myself included - believes that we could ever achieve total information awareness. But the government needs to set goals and long-range objectives. Total information awareness is a good goal.

One of the reasons I continue to speak out is that the solutions to the counterterrorism problem involve other parts of the national security community - especially other elements of the Department of Defense, State, FBI, Homeland Security and the staff.

We wanted to be as expansive as possible to make sure we didn't preclude some good ideas.

I really believe that we don't have to make a trade-off between security and privacy. I think technology gives us the ability to have both.

Uncontrolled access to data, with no audit trail of activity and no oversight would be going too far. This applies to both commercial and government use of data about people.

The problem we were struggling with within the closed market was what the incentive would be. You probably wouldn't use dollars. But those are all questions that need to be explored.
