Americans have always complained when a foreign diplomat is involved in a crime while they are in the US and get away with it by virtue of diplomatic immunity. Now the wife of a US diplomat stationed in the UK is involved in the death of a British citizen and she flees their jurisdiction claiming the same immunity. We can’t have it both ways. She should return to the UK and face whatever consequences are in store for her mistake. Stand trial and let the chips fall where they may. She was in the wrong, she knows it, and so do we.
