It was one of the biggest secrets of the post-9/11 era: soon after the attacks, President Bush gave the CIA permission to create a top secret assassination unit to find and kill Al Qaeda operatives. The program was kept from Congress for seven years. And when Leon Panetta told legislators about it in 2009, he revealed that the CIA had hired the private security firm Blackwater to help run it. "The move was historic," says Evan Wright, the two-time National Magazine Award-winning journalist who wrote Generation Kill. "It seems to have marked the first time the U.S. government outsourced a covert assassination service to private enterprise."
