and until the robots arrive, you have Blackwater and such:
"President Bush's 2001 executive order severed this line by transferring to the CIA his unique authority to approve assassinations. By removing himself from the decision-making cycle, the president shielded himself -- and all elected authority -- from responsibility should a mission go wrong or be found illegal. When the CIA transferred the assassination unit to Blackwater, it continued the trend. CIA officers would no longer participate in the agency's most violent operations, or witness them. If it practiced any oversight at all, the CIA would rely on Blackwater's self-reporting about missions it conducted. Running operations through Blackwater gave the CIA the power to have people abducted, or killed, with no one in the government being exactly responsible."
