Indeed! Well said :)
With all of those agencies, my guess is that it probably has something to do with shady dealings of a military/defense contract company in Charleston.
IIRC, some company called Blue Mountain Group was hired by State Dept. to protect compound like 2 weeks before Benghazi happened. I need to dig it up but I remember that the Blue Mountain Group was based in UK but invoices were billed from a Charleston SC address.
