What are you shocked about? The laughing staff members should clue everyone in that this is largely just a political football. Not only could they apparently not care less, they are such to the point that their smirks and grins, knowing full well they were being broadcast and/or recorded, could not be contained.
I feel for the families of the dead but let's be realistic, they shouldn't have been there. Was it incompetency that they were not pulled? Yes. It was not incompetency that they were there in the first place, though. They knew full well of the danger. They probably were directly aware of the CIA meddling as well.
I would unabashedly welcome Hillary Clinton to be indicted for her incompetence if Crimes Against Humanity (and a litany of others) are implausible (at best) but I find myself rather 'meh' on the topic. I'm not saying I don't care as it is an important example of the consequences of empire but it doesn't really touch upon the issues I'd like to see touched upon.
Having no personal vestment in the issue I can say with a certainty that those smirking and grinning ought to be fired. Yesterday.
And Hillary Clinton, Obama, Holder, Bush, Brzezinski, Gates, Clapper, Panetta, Brennan, Yoo, McChrystal, Alexander, McRaven, Powell, Rice, Hayden, Kissinger, Bill Clinton, George H. W. Bush,
et. al (there are well over a hundred more), ought to be tried for a variety of war crimes/crimes against humanity.
