Since the killings of 17 Iraqi civilians by Blackwater security contractors in Baghdad's Nisoor Square...lack of accountability of contractors has been a central issue...While yesterday's signing...of a[n]...agreement that reportedly expands the scope of Iraqi jurisdiction over U.S. government personnel and contractors is a step forward, much remains to be done by the U.S. government to hold its contractors to account. Today, a leading human rights organization unveiled a detailed, multi-phased blueprint for the next administration to effectively end private contractor impunity, in Iraq and elsewhere..."It's been over four years since Abu Ghraib and more than a year since Nisoor Square, and we are still waiting for prosecutions of the contractors implicated in these abuses..." said Massimino [Human Rights First's director]
