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.

The bottom line is how do we best provide for the security of the traveling public in light of a determined enemy who is adept at constructing well-designed, well-concealed devices which would not show up in a walk-through metal detector?
