Of course, Attorney General is normally a position with a high degree of autonomy, not one that just involves following the orders of a boss. And firing an Attorney General, while legal, is so rare that it's practically unheard of.What technicality are you talking about? Her boss asked her to do something, she refused, he took action against her insubordination. This happens in business all the time. People make their own ethical decisions and take responsibility for the consequences.
This DOESN'T happen all the time. Even in business, this - firing a high-level executive for not following a questionable order - is pretty rare.
