How did the Abu Ghraib abuse scandal become known and what was the immediate result?

Joseph Darby, Military Police, would uncover the abuse going on in Abu Ghraib when he asked MP Charles Graner for any interesting photos he's taken while in Iraq. While looking through two CDs he came across several pictures exhibiting the abuse taking place during Graner's nightshift. Darby reported the abuse to CID, he was told he would remain anonymous. The New Yorker and 60 Mins II would reveal the pictures of the abuse and would inform the world of the abuse within Abu Ghraib. After the scandal broke there was an immediate outcry form the arab world and from humanitarian organizations seeking justice for these crimes. Six soldiers were charged with the crimes that took place at Abu Ghraib. White House Administration deemed the acts of all these soldiers as the wrong doings of only these few soldiers and does not speak of the Army as a whole. Furthermore, that what occurred there was "Animal House on the nightshift". There was more to what happened in Abu Ghraib than what those soldiers did. It was a combination of failures that reached all the way to the White House, even if they were not directly involved in the abuse. In Seymour M. Hersh's news breaking article "Annals of National Security: Torture at Abu Ghraib" he states,  

"As the international furor grew, senior military officers, and President Bush, insisted that the actions of a few did not reflect the conduct of the military as a whole. Taguba’s report, however, amounts to an unsparing study of collective wrongdoing and the failure of Army leadership at the highest levels." Taguba suggested that high ranking Army officers, Military Intelligence officers and Civilian contractors be relieved of their duties and reprimanded. The soldiers that were directly involved with the abuse that occurred in Abu Ghraib do hold a majority of the blame for what happened, but it should be noted that they do not hold the entire blame.
