Awwal 08, 1432, Feb 11, 2011, SPA -- Pakistani police say their investigation into an American's fatal shooting of two Pakistanis in January has found that the man did not act in self-defense, according to AP. Lahore police chief Aslam Tareen says that Raymond Davis carried out «an intentional and cold-blooded murder.» The U.S. insists he has diplomatic immunity from any charge. Davis' arrest has strained U.S.-Pakistan relations. Washington insists Davis shot two Pakistanis dead because they were trying to rob him. Earlier Friday, a Pakistani judge ordered the American remain in custody for 14 more days and also told the government it must clarify whether the man has diplomatic immunity.
