Uh, that only works if it can be proven the CIA gave him the right information.
Right now, Petraeus has indicated the admin story line: it was a video protest turned rowdy.
Petraeus will cover for him, because I suspect there is more than just a Broadwell affair here. They have gone over his entire life with a comb.
And Petraeus can’t change his story now that he is a proven liar, as it relates to adultery.
The CIA has issued a statement some time ago that they never said anything about a protest over a ‘video.’ But that makes no difference whatsoever. They saw the attack live, heard calls from people on the ground and new both the consulate and annex were under a concerted attack. Are you saying a rescue mission should hinge on who is attacking and why they are attacking? I hope you’re not a police dispatcher in your town.
