Collaborators vs. insurgents, or patriots vs. terrorists?

"Al-Qaida’s arm in Iraq released a video Saturday showing its militants lining up five captured Iraqi security officers and executing them in the street, the latest move in a campaign to intimidate Iraqis and target those who collaborate with U.S.-led forces....

In the footage, one of the prisoners identified himself as Lt. Bashar Latif Jassim and said his mission was to "prevent terrorists from entering Iraq." When asked by one his captors -- who did not appear on camera -- who the terrorists are, Jassim said: "Those who sabotage the country."
