DUH!

The report states: "What the precise motivations were of those detainees who have returned to fighting is not clear."

Let's see, they consider themselves soldiers returning to duty?

In their view, this is a holy war, so, not to return to fighting would not only be treason, but tantamount to renouncing their faith?

The report, also, stated: "The United States has been massively criticised for detaining hundreds of prisoners at Guantanamo Bay."

Let's hear for Amnesty International, and other humans rights groups for not having a grasp of the fairly obvious!
