Explanation:

Most Army Reserve soldiers convicted of mistreating prisoners in Abu Ghraib were inexperienced young people who received defective and weak military training, where they were taught to mistreat prisoners of war in order to obtain useful information for the American government. This training was what caused these soldiers to present practices of torture and humiliation to prisoners in Abu Ghraib, where many of the prisoners they had were innocent and had been accidentally captured and had no idea why they were being subjected to inhumane activities.

Abu Ghraib prison was a British prison complex built in Iraq, when Iraq was an English colony. It was a scene of torture practices for prisoners in the British empire, in the government of Saddam Hussein and during the American occupation.
