Two years after U.S. forces shot to death Italian intelligence agent Nicola Calipari in Iraq, Washington is refusing to hand over the U.S. soldier charged in the case to be tried in Italy. Calipari was killed while escorting Italian reporter Guiliana Sgrena after securing her release from a month-long abduction in Iraq. Sgrena joins us in our firehouse studio to discuss the case.

Italy has criticized the Bush administration for failing to claim responsibility for the 2005 killing of Italian intelligence agent Nicola Calipari in Iraq. Speaking at a commemoration for Calipari on March 4th, Italian Foreign Minister Massimo D'Alema openly challenged the United States and said, "Right now, there is a need for justice to be done."

Calipari -- the number two man in Italian military intelligence -- died while escorting Italian reporter Guiliana Sgrena out of Iraq after securing her release from a month-long abduction. U.S. forces opened fire on their vehicle as they drove to Baghdad International Airport. Another agent and Sgrena were wounded in the attack.

Last month, a judge in Rome ordered New York Army National Guard soldier Mario Lozano to stand trial in Italy on murder charges, but Washington has refused to hand him over and considers the case closed. Lozano will be tried next month in absentia.

Giuliana Sgrena wrote about her experience in her book, "Friendly Fire: The Remarkable Story of a Journalist Kidnapped in Iraq." Sgrena is a veteran foreign correspondent for the Italian newspaper Il Manifesto and has reported frequently from Afghanistan and Iraq. She joins me in the firehouse studio.
