Here's what I think, in layman terms
Benghazi is complicated, could have been more secret ops going on than will ever know when this broke out. I would guess even more than Clinton was aware of (In detail anyways). There was support fire teams present near by that did not show up at Benghazi and I would guess it was because they were providing cover for something else(which they wouldnt abandoned)....not to mention all the spook **** going on that no ones supposed to know about. This looked sorta obvious to me right from the beginningish...but I'm postulating.
One thing that seems for sure ... Everyone went into cover your ass mode, and the winner of that event goes to Team Obama/Clinton. What really irks me is the intensity they put forth to purposely mislead us...I could have understood their F-up....but I guess that means they would have had to understand their F-up first
