This case has reached the point that, IMHO, both sides should now let Pakistani justice take it's course. Mr. Davis should never have killed those two men. He was totally wrong in his behavior on many, many levels. And diplomatic immunity should not be used as a cloak to protect scoundrels. The USA should voluntarily waive any claim to diplomatic immunity for Mr. Davis. The US State Department should now content itself with providing Mr. Davis the best legal representation that can be had and let Pakistan's Courts sort out the matter. As far as trading him for Aafia, that could realistically only come after Davis is convicted and sentenced. So, the best way out of this now is for Pakistan to bend over backwards to give Mr. Davis a speedy and transparently fair trial and let the chips fall where they may. Mr. Davis deserves all the anguish he is in. He brought it on himself.
