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.

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.

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.

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.

It would be ideal if we could have an uncontrolled flow of information. But we realized you can't do that.

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

I think if I had to do it over again, I'd do it the same way. I would just put more resources into getting the public diplomacy part much stronger than we were able to.
