Whatever they’re trying to cover up here is bigger than their fear of having the cover-up found out. IMHO.
Was it weapons running? Was it an attempt to have Stevens kidnapped and Obama work a deal to release the blind sheikh? Were they trying to have Stevens killed because he knew more than he should? What was really going on, that they’re trying to cover up? The fact of the cover-up is abundantly clear. But as long as the cover-up is the story, they’ve still succeeded in covering up.
We need to know what they are covering up.
We know the real reason they didn’t help our people was NOT because they didn’t have the resources available - because they DID have resources available, resources who were livid that they were not allowed to help.
So what was the REAL reason they wouldn’t help them? That’s what we need to know.
Was it an attempt to have Stevens kidnapped and Obama work a deal to release the blind sheikh?, Obama meets with Omar Abdel-Rahman (the Blind Sheik for those in Rio Vista) prior to release. 
Obama: " OK Abdel-Rahman, I got your one way to Cairo on e-bay"
Omar: "you may call me Omar"
Obama: "Thanks Omar...and I got you a disguise as those pesky FReepers have an eye out for you"
Omar: "Let me consult with you later on that"
Obama: "I got it covered, what with the FEMA camps and a billion rounds of ammo."
Omar: "Keep up the good work my brother from another mother"
Obama: "And how was the American culture field trip to a noodling competition ?
Omar: ..."I caught an alligator."
