What are the reasonings for the torture and executions at the Abu Ghraib prisons? Was it a work by only a few? Or does it represent a larger view of the U.S. Military or Government?

I will have to find different sources on the reasonings for the Abu Graib prison in the first place. And then maybe find interview or information fromt the soldiers about why they commited some of these acts and then overall look at the governments views.

How does American government reactions and court proceedings to the atrocities at Abu Ghraib by American soldiers reflect their views on torture and International prisons as a whole?

I would have to look at the actual cases and court procedings for soldiers and then see how the U.S. reacted.
