CBC Fifth Estate recently did a documentary about the torture at Abu Graib called A FEW BAD APPLES. Here is a summary of the program as well as a link to the video itself, it is a must watch, imo.

ONE NIGHT OF ABUSE
The fifth estate's story, "A Few Bad Apples", unravels the events of one night—October 25, 2003—events captured in one of those famous photographs. Three Iraqis, detained by American soldiers at the prison, are dragged from their cells, made to crawl naked along the floor and chained together on the ground and forced to mimic sex. More soldiers gather. Some participate in the humiliation of the detainees, others stand by and watch.
"A Few Bad Apples" tells the story of the soldiers in that photograph—some of the "bad apples" that the White House argued were, alone, responsible for the abuses in Abu Ghraib—as well as another, bigger, story about politics and the war in Iraq.
A NEW INTERROGATION POLICY
The quick victory predicted by many Pentagon officials did not materialize after the invasion of Iraq. The country became ever more violent and dangerous. Caught unprepared, American forces scrambled to gather intelligence against a new, shadowy enemy.
Aggressive interrogation policies that contravened the Geneva Conventions were condoned and, in many instances, encouraged by the highest levels of the American government. High-level commanders insisted detainees be "broken". Soldiers in the field now understood that the "gloves coming off."
