The conspirators - rightwing extremists who were caught with forged identity passes to the United Nations and the Pentagon, and a variety of racist and anti-government pamphlets - have refused to cooperate with investigators, who believe others involved in the plot may still be at large.
A series of anthrax letter attacks which took place in the weeks after September 11 2001 are also thought by FBI investigators to have been the work of an American fanatic. The case has not yet been solved and has similarly been largely forgotten.
So yeah-- those three got caught. How many other domestic terrorists are out there and are we spending as much time looking for them as we are for the international terrorists? I think we need to have an equal focus on BOTH international and domestic terrorists. I think that is the point some of us are trying to make.
And btw,it may be that law enforcement officials ARE equally focusing on both international and domestic terrorists, but the media certainly isn't.
