John S. Pistole: “it is not a question of if but when there will be an attack here on the homeland.”

the fact remains accurate through today and underscores a point that in aviation security, it is not the object per se that is dangerous but the individual who intends to use that object to inflict harm that presents the danger.

The goal is to focus on those who present the greatest risk.

I believe strongly in behavior detection, the observation of individuals, and we have a number of officers trained in that regard.

We face a determined enemy which constantly evolves its tactics and techniques, and as we have seen the threat is real.
