I believe there to be more to this story than meets the eye. The Associated Press reported on Sunday after the shooting:
In an interview with RAI, Italian state television, Sgrena recounted her final moments before freedom: "When they let me go, it was a difficult moment for me because they told me, `The Americans don't want you to return alive to Italy.'"Did the kidnappers release her, and then pass word to the Americans that a suicide bomber was on the way to the airport? Did the kidnappers get a double whammy for their efforts? They received a hefty ransom from the Italian government, which they use to obtain more terrorist weaponry to be used against the Iraqis and Americans, and, at the same time, create a backlash against the war and America in Italy? This hypothesis comes from Robert L. Simon, and it is a good one.
