The tense saga of Raymond Davis, who shot and killed two Pakistanis in Lahore on January 27, continues. His trial in Lahore has been delayed again, with the next hearing date addressing the question of diplomatic immunity now set for either March 3 or March 14, depending on which report you believe. On Wednesday, Senator John Kerry visited Pakistan to deliver yet another threat of Congress cutting off funding for Pakistan if Davis is not released. In the meantime, analysis of records for the “businesses” with which Davis is associated in the US raises the interesting question of whether he recruits potential spies among students taking courses in international security.
