In April, US forces laid siege to Falluja in retaliation for the gruesome killings of four Blackwater employees. The operation was a failure, with US troops eventually handing the city back to resistance forces. The reason for the withdrawal was that the siege had sparked uprisings across the country, triggered by reports that hundreds of civilians had been killed. This information came from three main sources: 1) Doctors. USA Today reported on April 11 that "Statistics and names of the dead were gathered from four main clinics around the city and from Falluja general hospital". 2) Arab TV journalists.

While doctors reported the numbers of dead, it was al-Jazeera and al-Arabiya that put a human face on those statistics. With unembedded camera crews in Falluja, both networks beamed footage of mutilated women and children throughout Iraq and the Arab-speaking world. 3) Clerics. The reports of high civilian casualties coming from journalists and doctors were seized upon by prominent clerics in Iraq. Many delivered fiery sermons condemning the attack, turning their congregants against US forces and igniting the uprising that forced US troops to withdraw.

"We don't do body counts," said General Tommy Franks of US Central Command. The question is: what happens to the people who insist on counting the bodies - the doctors who must pronounce their patients dead, the journalists who document these losses, the clerics who denounce them? In Iraq, evidence is mounting that these voices are being systematically silenced through a variety of means, from mass arrests, to raids on hospitals, media bans, and overt and unexplained physical attacks.
