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.

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

I want to take TSA to the next level.

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.

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.

The reason we are doing these types of pat downs and using the advanced imagery technology is trying to take the latest intelligence and how we know al Qaeda and affiliates want to hurt us, they want to bring down whether it is passenger air craft or cargo aircraft.
