Maria actually laughed, startled and harsh, at Queen's idea of what was going to happen. "After having worked for the CIA, you still think they'll abide by the law?" she asked, somewhat rhetorically. Of course the CIA wasn't going to explain what they were doing with a US citizen in a foreign country; they were in the business of secrets, after all. But that didn't mean that they wouldn't also extract punishment. "Mr Queen, they're not interested in imprisoning you. They'll just shoot you. Given how long you've been off most people's radar," she continued, almost thoughtfully, "they won't have too much trouble making you just vanish." A few papers, and it would look as though he walked away on one of his mid-life crises to an island somewhere, certainly wasn't sunk in a harbor with a few bullets in his brain.
When they wanted to be, the CIA operated very much like an organized criminal enterprise. She didn't always like that it forced SHIELD to operate much the same way, but secrets and spies went together, and even she didn't tell Congress what every line in the budget was for.
If one of those lines had to be 'bribe Robin Hood-type to cooperate', so be it.
Her phone buzzed on her knee, and she glanced down before briefly tapping an answer; her fingers were still finding words on the keypad as she looked up to answer Queen. "Besides the whole 'dead or vanished' bit," she had to point out, because that should feature high on his list, "I can promise SHIELD doesn't try to topple a rebellion. Unless you count HYDRA and AIM as rebellions against the known world order." They weren't very ethical, but at least they had a different focus than the CIA.
