The limitation to international terrorism in existing law is an impediment
to the effective use of national security letters because it may not be
apparent in the early stages of a terrorism investigation-or even after it
has continued for some time-whether domestic or international terrorism is
involved. The Oklahoma City bombing and the anthrax letter incidents
illustrate this point. Moreover, in the current circumstances, domestic
terrorists who attempt to ally with or are inspired to emulate
international terrorists are an increasing concern. The dangers posed to
the national security by such persons may be comparable to those posed by
international terrorists, and national security letters should likewise be
an available tool in the investigation of their criminal activities.
