They already know the golden rule: The ACLU
This administration would publicly crucify any agent who steps out of line and probably turn them over to the ICC for prosecution and the agents know it.
That is why the administration would never know. In an event like this, the error is to do it and cover up afterward. The proper way is to have your paperwork in order first, then go ahead. The trick is to turn what some might consider an illegal act into the bureaucratic equivalent of arguing tactics.
Revenge should not only be served cold, but it should be on a soft bed of bureaucratic paper, and smothered in complexity sauce.
