The Obama administration didn’t actually believe the spontaneous-riot story they were using publicly:
In a briefing to Capitol Hill staffers delivered the day after the deadly Sept. 11 attack in Benghazi, a top aide to Secretary of State Hillary Clinton said the killings appeared to be the result of a terrorist attack. . .
That a State Department official of Kennedy’s rank . . . reached so swiftly the conclusion that the attacks were premeditated and coordinated stands in stark contrast to the opposing narrative pressed at that time, and for several days afterward. . .
Three days after Kennedy’s conference call, for example, U.S. Ambassador to the United Nations Susan Rice appeared on five Sunday morning talk shows to insist that the attacks were neither coordinated nor premeditated, but were rather the result of a spontaneous mob action. . . Rice has since told lawmakers that her comments reflected “the intelligence community’s best, current assessment as of the date of my television appearances. . .”
I actually find this reassuring. I hate dishonesty, but I think I prefer it to the kind of incompetence it would have taken actually to believe their story.
