And these military trials are also less efficient, noted Laura Pitter, Counterterrorism Advisor for Human Rights Watch:  "The attacks of 9/11 were a great tragedy for all Americans and without doubt a crime that must be prosecuted. But it's disturbing to watch that horrific crime so dramatically change the U.S. system of justice - a source of pride for so many Americans. It's more disturbing given that it's not necessary or prudent. Federal courts have completed hundreds of terrorism cases since 9/11, while the commissions have dispensed with a mere seven."
