WASHINGTON — The courtroom monitors carried theimageofasmiling9-yearold boy as his father pleaded for the punishment of four U.S. governmentcontractors convicted in shootings that killed that child and more than a dozen other Iraqi civilians.

“What’s the difference,”

Mohammad Kinani al-Razzaq asked a Washington judge at an emotional 2015 sentencing hearing, “between these criminals and terrorists?”

The shootings of civilians by Blackwater employees at a crowded Baghdad traffic circle in 2007 prompted an international outcry, left a reputational black eye on U.S. operations at the height of the Iraq war and put the government on the defensive over its use of private contractorsinmilitaryzones.

The resulting criminal prosecutions spanned years in Washington but came to an abrupt end Tuesday when President Donald Trump pardoned the convicted contractors — an act human rights activists and some Iraqis decried as a miscarriage of justice.

The news comes at a delicate moment for the Iraqi leadership, which is trying to balance growing calls by some Iraqi factions for a complete U.S. troop withdrawal from Iraq with what they see as the need for a more gradual drawdown.

The United Nations’ Human Rights office said Wednesday that it was “deeply concerned” by the pardons, which it said “contributestoimpunityand has the effect of emboldening others to commit such crimes in the future.” The Iraqi Foreign Ministry said the pardons “did not take into account the seriousness ofthecrimecommitted,” and that it would urge the U.S. to reconsider.

Al-Razzaq, the father of the slain boy, told the BBC that the pardon decision “broke my life again.”

Lawyers for the contractors, who had aggressively defended the men for more than a decade, have long asserted that the shooting began only after the men were ambushed by gunfire from insurgents and then shot back in defense. They have pointed to problems with the prosecution — the first indictment was dismissed by a judge — and argued that the trial that ended with their convictions was tainted by false testimony and withheld evidence.

Though the circumstances of the shooting have long been contested, there is no question the Sept. 16, 2007,episode—whichbegan after the contractors were orderedtocreateasafeevacuation route for a diplomat afteracarbombexplosion— wasalowpointforU.S.-Iraqi relations.

The FBI and Congress opened investigations, and the State Department — which used the Blackwater firm for security for diplomats — ordered a review of practices.

Robert Ford, who served as a U.S. diplomat in Iraq over five years, met with the widows and other relatives of the victims after the killings, handing out envelopes of money in compensation and formal U.S. apologies — though without admitting guilt, since investigations were ongoing.

“It was one of the very worst occasions I can remember in my time” in Iraq, said Ford, who teaches at Yale University.

The widows mostly took the envelopes silently. Some of the adult male relatives of those killed spoke up, bitterly. “How could you do this? We must have justice,”

Ford recounted Wednesday.

Adding to the angry fallout among Iraqis was the involvement of Blackwater, a security firm founded by Erik Prince, a former Navy SEAL who is a Trump ally and brother of Education Secretary Betsy DeVos. The company had already developed an unfavorable reputationforactingwithimpunity, itsguardsfrequentlyaccused of firing shots at the slightestpretext, includingtoclear their way in traffic.

A review of Blackwater’s incident reports in 2007 by House Democrats found Blackwater contractors reportedtheyengagedin195 “escalation of force” shootings over the preceding two years — with Blackwater reporting its guards shooting first more than 80% of the time.
