I still think that what is being hidden is something to do with the CIA. The murdered Ambassador had been in Libya doing who knows what for months before the final overthrow of Gaddafi and his appointment as Ambassador. He was very aware of the intensity of the risks. He went to Benghazi of his own volition. I have seen photos of the US compound there, it looked very vulnerable. He undoubtedly knew the overall risk situation, but did not get adequate intelligence on the apparently planned attack in time to react. While on the subject, how did the CIA manage to loose the maps to the Bora Bora caves which could have led to an early capture of bin Laden. That probably could have prevented the suggestion that a war in Iraq was needed from being agreed with by most Americans. Of course, then Halliburton, Black Water and others would not have made so much money.
Am looking only at one POI at this time. The visit made that night of the attack by the turkish ambassador. But to get at the truth, water-board would have to be allowed. That will not happen though.
