Appalling Evidence of Torture

This via Balkinization. The Washington Post has a lengthy article about the death of Iraqi Maj. Gen. Abed Hamed Mowhoush. The Major General was captured during a raid after walking onto a base to negotiate the release of his sons. He then died of natural causes after being brutally beaten multiple times. It's simply disgusting to read. It's becoming increasingly clear that the use of thuggish, stand-in torturers (in this case the Scorpions) has been systematic. And it looks like a handful of low level troops are going to take the fall for actions they were led to believe were authorized from higher levels.

My question is this: If an Iraqi Major General is not protected by the Geneva Conventions, who is?
