Then perpetuitously you'd have to eliminate the similarly low-crime 'burbs of Baghdad..then omit any other dissimilarities and so on and so on. Might as well throw the "comparison out altogether.
So I leave on this thought. Should you have to choose one, would YOU prefer the level of US city violence in your 'hood or that of Iraq?
That is why its only good as a general demonstration. The demonstration that Iraq is not a sinking quagmire of total violence as portrayed in the MSM. ANd that is his point.
