The directors for these agencies are appointed by the President. He hand picks them, and has the ability to fire them with adequate cause, of which there is recent precedent. I am not sure how you can argue they are not controlled by the President, unless you want to try some sort of secret-blackmail theory. However, it isn't surprising that the FBI or similar agencies are full of egocentric people who believe they hold the power in the relationship. It seems to attract these types of people, really.
