re: Trying one last time.
I'm sure there are incidents that weren't reported. I'm equally sure there are "civilian" casualties in incidents that were anything but. The only difference between an insurgent combatant and a non-combatant in Iraq is somebody grabbing the AK-47 to sell on the black market before the bodies are collected.
Why, as long as we're dealing with imaginary numbers, I can claim with no fear of having it proved otherwise that these two things pretty much cancel each other out.
