Another U.S. soldier implicated in the abuse of Iraqi prisoners at Abu Ghraib prison says she was just following orders.

In an e-mail printed in the Washington Post, Spec. Sabrina Harman -- who was a military police officer -- said, "They would bring in one to several prisoners at a time already hooded and cuffed" -- referring to 'they' as CIA, Army intelligence officers or contractors handling interrogations.

"The job of the MP was to keep them awake, make it hell so they would talk.

"The person who brought them in would set the standards of whether or not to 'be nice.'"

Harman, a 26-year-old reservist who is the assistant manager of a pizza restaurant in civilian life, was the grinning woman in a picture with a pyramid of naked men.

She is one of seven military police reservists who has been charged in connection with the incident.

According to the Post, she was the person who told one prisoner if he fell off a small box, he would be electrocuted.

The revulsion and outrage, particularly in the Arab and Muslim world, has led to apologies from U.S. President George Bush and U.S. Defense Secretary Donald Rumsfeld.

Paul Bremer, the top civilian administrator in the Coalition Provisional Authority, said, "no society is without its evil people."

In his testimony before the Senate and Congressional Armed Services committees Friday, Rumsfeld said guards shouldn't be used for interrogation, and that "in the case of Iraq, they should adhere to the Geneva Convention."

In Iraq, Maj. Gen. Geoffrey Miller, the new commander of prisons there, said, "what me must do now is not only use words, but our actions must demonstrate our continuing focus on this, our adherence to the Geneva Conventions."

He blamed the debacle on poor leadership and a disregard for the rules.

Janis Karpinski, the officer he replaced, has said she knew nothing of the worst abuses and that military intelligence kept one wing of Abu Ghraib -- which was a prison used for torture in the time of former Iraqi dictator Saddam Hussein -- under its own control.

For her part, Harman claims to know nothing about the Geneva Conventions.

"The Geneva Convention was never posted, and none of us remember taking a class to review it.

"The first time reading it was two months after being charged," she said. "I read the entire thing, highlighting everything the prison is in violation of. There's a lot."

For example, Article 1(d) bans "outrages upon personal dignity, in particular, humiliating and degrading treatment." In Article 13, "prisoners of war must at all times be protected, particularly against acts of violence or intimidation and against insults and public curiosity."

Moving forward, Miller said a team of 31 specialists would be in Iraq helping train prison guards.

He curtailed the use of some of the most aggressive interrogation techniques, such as forcing prisoners to wear hoods and depriving them of sleep -- although they still might be utilized in some circumstances.

Under Article 17, "No physical or mental torture, nor any other form of coercion, may be inflicted on prisoners of war to secure from them information of any kind whatever. Prisoners of war who refuse to answer may not be threatened, insulted, or exposed to any unpleasant or disadvantageous treatment of any kind."

With respects to military police -- such as Harman -- they "should be involved in passive intelligence collection," Miller said.
