More than seven years after guards with the private mercenary company Blackwater opened fire on Iraqi civilians in downtown Baghdad, killing 17 people and wounding 20, a federal jury on Wednesday found four of the men involved with the massacre guilty in the case.Former guard Nicholas Slatten was handed a guilty verdict for first-degree murder, the Associated Press reports. The other men—Paul Slough, Evan Liberty and Dustin Heard—were all found guilty of voluntary manslaughter.The men were employed by the U.S. State Department at the time of the massacre at Baghdad’s Nisour Square on September 16, 2007. Their victimes include 9-year-old Ali Kinani—killed by a gun shot to the head. Reported as the largest known massacre of Iraqi civilians by U.S. private contractors, the incident became a flashpoint of outrage over the atrocities that U.S. forces—particularly mercenaries—inflict on occupied civilian populations in Iraq.The guilty verdicts follow years of legal battles, in which plaintiffs were left unsure of whether the defendants would ever face trial. Seventy-two witnesses were summoned for the trial, including Iraqis victimized by the attack. Though seventeen people were killed, the trial related to the slaughter of 14 Iraqis and wounding of 17.During his closing argument against the Blackwater guards, federal prosecutor Anthony Asuncion said: “These men took something that did not belong to them: the lives of 14 human beings. They were turned into bloody bullet-riddled corpses at the hands of these men.”Advocates for the victims welcomed the ruling.\u0022While today’s verdict cannot bring back the innocent Iraqis killed at Nisoor Square, it is a step towards full accountability for Blackwater’s actions,\u0022 said Baher Azmy, Legal Director for the Center for Constitutional Rights, which represented Iraqi victims of the killings in a human rights suit against Blackwater that settled in January 2010.\u0022However,\u0022 Azmy added, \u0022holding individuals responsible is not enough. If corporations like Blackwater, now known as Academi, are granted the rights accorded to \u0026#039;people\u0026#039; they must also bear the responsibilities.\u0022Dan Roberts, who has covered the trial closely for the Guardian newspaper, reports from Washington that all the men now \u0022face the likelihood of lengthy prison sentences after unanimous verdicts on separate weapons charges related to the incident.\u0022Scahill, who has written extensively about both Blackwater and the Nisour Square massacre, responded to the verdict at The Intercept by writing, \u0022Just as with the systematic torture at Abu Ghraib, it is only the low level foot-soldiers of Blackwater that are being held accountable.\u0022 Scahill points out that Blackwater founder and former-CEO Erik Prince and other high-ranking Blackwater executives remain free and that no U.S. officials from the Bush administration were ever held\u0026nbsp; responsible for \u0022creating the conditions for the Nisour Square shootings.\u0022According to Azmy, \u0022Private military contractors played a major role in the pressure to go to war in Iraq and have engaged in a variety of war crimes and atrocities during the invasion and occupation, while reaping billions of dollars in profits from the war.\u0026nbsp; To this day, the U.S. government continues to award Blackwater and its successor entities millions of dollars each year in contracts, essentially rewarding war crimes.\u0022As noted by the Guardian\u0026#039;s Roberts, the 14 victims killed by the Blackwater guards on trial were listed as Ahmed Haithem Ahmed Al Rubia’y, Mahassin Mohssen Kadhum Al-Khazali, Osama Fadhil Abbas, Ali Mohammed Hafedh Abdul Razzaq, Mohamed Abbas Mahmoud, Qasim Mohamed Abbas Mahmoud, Sa’adi Ali Abbas Alkarkh, Mushtaq Karim Abd Al-Razzaq, Ghaniyah Hassan Ali, Ibrahim Abid Ayash, Hamoud Sa’eed Abttan, Uday Ismail Ibrahiem, Mahdi Sahib Nasir and Ali Khalil Abdul Hussein.
