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

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.

We put people of concern on the watch list or the no-fly list, so we have a number of layers of security beyond the airport checkpoint. We gather as much information about a passenger as the law allows without profiling.

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.

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.

I want to improve TSA's counterterrorism focus through intelligence and cutting edge technology, support the TSA workforce, and strengthen the agency's relationships with stakeholders and the traveling public. All of these priorities are interconnected and are vital to TSA's mission - and I would say, all of our collective mission.

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.
