I am skeptical of any numbers from a war zone with a public relations war going on at the same time. This appears to be generally admitted, as witnessed by quotes as the long standing and cross cultural "the first casualty of war is truth." [1]
So I'm curious. How do you know the numbers are factual and they eye witnesses are what they say they are?
