The investigation of the terrorist attack on the U.S. Consulate in Benghazi, Libya, is beginning to look disturbingly familiar. After President Obama promised “justice” for the killing of Ambassador J. Christopher Stevens and three other Americans, FBI agents were dispatched to the country. But it was three weeks before they made their first visit to the site — which had been left unsecured. Libyan authorities have arrested several people, but it is not clear whether they had any role in the assault. Meanwhile, Libyan officials appear to be resisting direct U.S. involvement in the investigation.
