Christian Science MonitorPakistani officials contend that Davis’s diplomatic status remains unclear. Reports that Davis was formerly a member of the US special forces, as well as his competence with a handgun shown in the shooting, have fueled rumors that he may be part of a larger American covert military effort in Pakistan, The Financial Times reports. Lahore’s police chief, Aslam Tareen has also stated that his department now has evidence Davis killed in “cold blood,” not self-defense.
“Raymond Davis fired ten bullets,” said Mr. Tareen. “The evidence shows that this was a cold-blooded murder. It was not a self-defense case, it was clear-cut murder.”
Although Pakistani officials appear unwilling to grant Davis diplomatic immunity, The New York Times reports that Pakistani officials have privately acknowledged that Davis, who holds a diplomatic passport, is protected by the Vienna Conventions. In the face of fierce public opposition, however, senior American officials say their Pakistani counterparts “appear unable or unwilling to enforce the protocol.”Some of the strongest protests against releasing Davis have come from Pakistan’s Islamist community, which has used the case to paint the current government as a "stooge" of the US, according to the Financial Times.
