Well, he was lucky!

The identity of the CIA station chief that was accidentally revealed, did manage to leave Pakistan.

If he had remained behind then this:

would have happened to him.

I am sure the trial would have gone very badly for him.

As for the trial itself, it would have pulled the U.S. pants and under pants down to the ankles and exposed the U.S. bum for all its extra-judicial bummery doings.
