How did the Abu Ghraib prison abuse happen?

The Washington Times has a story on how things at Abu Ghraib prison deteriorated to the point where the abuse could happen. It was not due to evil people deciding to be mean, but the start was a bureaucratic decision because the correct thing to do, relieve the army commander in charge would be too politically difficult. The commander was Brig. Gen. Janis Karpinski, one of the highest female officers in Iraq and the Army.

By taking the easy way out, the Army created a much larger problem.
