Our pat-down approach is very similar to what is being utilized in Europe and, as we know, around the world. It's even much more thorough in other parts of the world.

But what I want to assure and reassure the public is we are concerned about your safety, your security, and your privacy. Let's work together in partnership to ensure that we can have the best way forward.

We save limited resources in terms of who we are physically screening. The approach will allow us to pay more attention to those potential terrorists.

And so we try to address those concerns in every way possible, recognizing, again, in the final analysis, everybody on that flight wants to be assured with the highest level of confidence that everybody else on that flight has been properly screened, and including me and you and everybody.

I particularly recognize that reasonable people can disagree as to what that proper balance or blend is between privacy and security and safety.

I did not want to provide a blueprint or roadmap for the terrorists, saying 'Here are our new security procedures'.

We want to be sensitive to people's concerns about privacy about their personal being and things, while ensuring that everybody on every flight has been properly screened.
