Iraq War Vets talk about random civilian killings

"Excerpts: Newsnight follow a group of former US soldiers who have returned from Iraq deeply affected by the experience. As they march ... all across America to protest, shocking interviews emerge on the indiscriminate killing of Iraqi civilians. Veterans reveal they had been trained to see Iraqis as animals, shoot up the landscape and kill anything that moved. Shovels and guns were carried by patrols in order to give the false impression that innocent killed civilians were actually up to no good - supposedly killed whilst digging holes for IED's."
