LBN-POLITICAL BRIEFING By THOMAS L. FRIEDMAN - 23 Dec 2004: There has been so much violence in Iraq that it's become hard to distinguish one senseless act from another. But there was a picture that ran on the front page of this newspaper on Monday that really got to me. It showed several Iraqi gunmen, in broad daylight and without masks, murdering two Iraqi election workers. The murder scene was a busy street in the heart of Baghdad. The two election workers had been dragged from their car into the middle of the street. They looked young, the sort of young people you'd see doing election canvassing in America or Ukraine or El Salvador.One was kneeling with his arms behind his back, waiting to be shot in the head. Another was lying on his side. The gunman had either just pumped a bullet into him or was about to. I first saw the picture on the Internet, and I did something I've never done before - I blew it up so it covered my whole screen. I wanted to look at it more closely. You don't often get to see the face of pure evil.There is much to dislike about this war in Iraq, but there is no denying the stakes. And that picture really framed them: this is a war between some people in the heart of the Arab-Muslim world who - for the first time ever in their region - are trying to organize an election to choose their own leaders and write their own constitution versus all the forces arrayed against them.
