Rome, March 20 - Rome prosecutors on Wednesday moved to have a technical review of the computer and the camera aboard the Enrica Lexie ship, where two Italian marines allegedly shot two Indian fishermen on another vessel off the coast of India one year ago. The men, Massimiliano Latorre and Salvatore Girone, were later questioned by a military prosecutor. They are at the center of an international row between India and Italy, which is refusing to return them for a homicide trial after India granted them a four-week travel permit to vote in Italian elections last month. It was the second such good-faith permit. India gave a similar waiver during the Christmas season, after which the pair returned. Both times the men had signed a form vowing to return for trial. After the announcement last week the men would remain in Italy, the Indian Supreme Court ordered the Italian ambassador there not to leave the country. Italy has long argued that the marines, who mistook the fishermen for pirates, should not be tried in India as the incident took place in international waters. Italy has also called for an international arbitrator to assess the case.
