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.

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.

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.

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

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.

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.
