In Vietnam, we reported random dead villagers as Viet Cong troops. In Afghanistan, we paid good money for anybody the Northern Alliance brought us, and shipped the prisoners off to indefinite detention at Camp X-Ray. In Iraq, we're apparently killing anybody who's in the wrong place at the wrong time, and then planting weapons on the bodies.
Mark Kraft (Metafilter's insomnia_lj) has a set of 16 photos (warning: graphic) of several Iraqi teens killed or wounded in Buhriz by American troops following an attack by small arms and RPG's -- typical insurgent weaponry. He sent the photos to Seymour Hersh, who determined that he couldn't really do anything with them, before releasing them on the web himself. (Also included are some relevent al-Jazeera and AP photos.)
Compare the first image with the tenth to see what happened after the American soldiers responded to what they thought was the source of the attack.
Whenever I hear about how we're coddling killers in Abu Ghraib and Camp X-Ray, this is what I think of. We know nothing about those prisoners and we're not especially interested in learning more.
