Heretofore, we always thought of our greatest national security threats as being external. Now, however, the threat is pervasive, i.e., internal as well. As the attacks of September 11, 2001 exhibited, the old methods of collecting and analyzing information have failed to protect us from the terrorist threat. While new technologies exist to counter terrorism, there is a hesitation to accept many of these for fear that they intrude upon personal privacy. Hence, the Potomac Institute is seeking to create the policy paradigm that will allow for the use of new information technologies that will enable the disruption of terrorist before they occur, while protecting our fundamental civil liberties.
