I am not surprised that Teribus clings to the IBC. From the Guardian link above:
"Only the conservatively calculated Iraq Body Count death toll credits the occupation with an average annual rate that is less than that - some 18,000 deaths in the five years so far. Every other source, from the WHO to the surveys of Iraqi households, puts the average well above the Saddam-era figure."
So, if IBC has ripped the Lancet study to shreds (a matter of opinion), they still need to rip the Baltimore study, the WHOI study, the ORB study, and the director of the Baghdad morgue.
