Ms. Harris is a disappointment.
At the same time, our Task Force recommends that all three governments define and defend a continental perimeter. This means that all three governments have to have confidence that a terrorist has no more chance of entering their own country as their neighbors. A common exclusion list, better intelligence-sharing, and combined training are needed. The three governments should establish a North American Customs and Immigration Force, composed of officials trained together in a single professional school, and they should fashion procedures to streamline border-crossing documentation. The Department of Homeland Security should expand its mission to include continental security a shift best achieved by incorporating Mexican and Canadian perspectives and personnel into its design and operation.
Voila. The elimination of the borders of the United States of America.
Outrageous!
