Jim Lampley at the Huffington Post says this:
A Bush-watcher website identified as TBRNews.org is reporting under the byline of "domestic intelligence reporter" Brian Harring that the Department of Defense is using a cynical tactic to mislead the public regarding the true death toll for American military personnel in Iraq. Harring claims he has an internal pdf. file from the D.O.D. which establishes that nearly 9000 Americans have died in Operation Iraqi Freedom, but that the official number has been held to 1713 by designating as Iraq deaths only those who perish on Iraqi soil. The remainder, he says, are military personnel who have died en route to Germany or in German hospitals-- casualties of the war, but not listed in the official death toll.
If this is true it would explain the apparent statistical discrepancy between dead and wounded. A combat action which produces nearly eight times as many officially wounded-- 13000 plus-- as officially dead...well, it's not the norm. It goes without saying it would also further jolt a public majority already disturbed by the war's "progress" and eager to see the troops come home.
