There are a number of aspects to the effectiveness of biometrics. There's the policy side of things. There is the technology side of things. There are the standard operating procedures that one might use to control the flow of people and provide the interdiction and get the intelligence and get a system to work as a whole with the various departments that do the collection of biometrics.
The best example I've seen so far is that of our neighbour to the south. They have invested a lot in the development of biometrics. We owe them a great debt for that, because otherwise the technology wouldn't have evolved as quickly. They've also provided a model for us to follow in various aspects, integrating databases of the Department of Defense, Department of Homeland Security's US-VISIT, and the FBI. We saw that model in action in a recent visit to eight agencies in the U.S. that collect and manage biometrics. I was very impressed. It does work. It works very well. It's a matter of implementing the right policies and procedures, in my view.
