The core issue remains the fact that Mr. Davis is under a US Diplomatic Passport with valid Pakistani Foreign Office VISA thereon, otherwise he could not//would not have been able to be in country there in Pakistan.
That two robbers failed in an armed stick up of Raymond Davis, who for fear of his life and limb, fought back is completely ignored by the writing public here in the main it seems.
There is a tired old joke which best describes some on this site and their "blather." An American victum is buried in a hole up to his neck, cannot move arms or legs, these are buried under ground. A group of six or so Pakistanis are circling the buried up to his neck American, hitting him all over parts of his only exposed part, his head. Whack, thump, whack. Then one "brave" Pakistani bends down close to the buried up to his neck American and says in his face: You are a vile person and we will 'get even' with you...at which point the buried American reaches his head forward and bites the Pakistani's ear off. The wounded Pakistani pulls back in a stream of blood and pain and he and his five bully Pakistani thugs shout: "Fight fair American!"
Nothing has changed on behalf of the US facts per our US Ambassador and the US Department of State regarding the fact that Ramond Davis has Diplomatic Immunity.
Some folks on this thread, largely from outside Pakistan, safe in overseas Western style democracy locations, are visibly bent on trying to "hang" Mr. Davis to satisfy what in fact is a tiny crowd of tire burners in Lahore. They constitute the fictional ring of Pakistanis circling and beating up a buried up to his neck Raymond Davis, who both has Diplomatic Immunity and who only defended himself from two armed robbers who threatened his life and limb in their failed stick up attempt.
