About 10 percent of the 150 English-speaking guards employed at the embassy by ArmorGroup, a private security company headquartered in Britain and Florida, approached the Project on Government Oversight and described “a pervasive breakdown in the chain of command and guard force discipline and morale,” according a letter sent to Clinton by executive director Danielle Brian.

An e-mail from one of the guards described parties on days off, during which guards and their supervisors urinated on themselves and others and ate potato chips and drank vodka from the cracks of buttocks.

“You will see that they have a group of sexual predators, deviants, running rampant over there,” one guard, whose name was withheld, said in an e-mail to POGO, adding, “They are showing poor judgment.”
