I want to take TSA to the next level.

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

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

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

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.

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.
