I don't think anyone is "shrugging it off".
I hope those responsible are tried and punished to the full extent of the law, commensurate with the damage they have caused to the situation in Iraq.
I think our leadership has correctly expressed our disappointment and outrage against the perpetrators.
OTOH, I don't accept the idea that this is "typical" or "standard" behavior for US forces. Nor do I accept the idea that these things were done "systemically", IE: that this was a standard, ordered-from-above method of dealing with prisoners.
Further, I think that those who attempt to paint it as "typical" or "standard" behavior probably have a different agenda rather than just protesting these acts.
Rumsfeld did not describe the photos, but U.S. military officials told NBC News that the unreleased images showed U.S. soldiers severely beating an Iraqi prisoner nearly to death, having sex with a female Iraqi female prisoner and “acting inappropriately with a dead body.” The officials said there was also a videotape, apparently shot by U.S. personnel, showing Iraqi guards raping young boys."
Yes, more bad news. However, I'm sure that the people responsible will be punished as I mentioned above.
If anyone wishes to make the case that an army in a similar situation exists or has existed that has/had absolutely no "bad apples" and no disgusting incidences of this kind, feel free to do so.
It's a terrible thing; it's disguting that it happened at all. It's been discovered, action taken, apologies made, restitution discussed and punishment of the guilty will result.
What else do you want?
