The bottom line is, if somebody doesn't go through proper security screening, they're not going to go on the flight.

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.

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.

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.

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.

I want to take TSA to the next level.

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