HARI SREENIVASAN:

Some two weeks after 9/11, Mohamedou Slahi, a 30-year-old electrical engineer, was arrested at his home in the North African country of Mauritania. He was questioned by FBI agents and then released.

In November of that year, he was re-arrested for suspected connections in a plot to bomb the United States. What followed was a harrowing journey through the American national security apparatus post-9/11, from Mauritania to Jordan to Bagram Air Force Base in Afghanistan, finally to the U.S. prison site at Guantanamo Bay. He remains there today, 13 years later, with no charges filed against him.

In 2005, he began a journal, which was confiscated by prison guards and deemed classified. After a seven-year legal battle, a federal judge declassified the material, although some sections remain redacted.

Last week, Little, Brown and Company published "Guantanamo Diary," in Slahi details those first years of imprisonment, including isolation, beatings, sexual abuse, and humiliation.

Joining me now are Slahi's lawyer, Nancy Hollander, and the book's editor, Larry Siems.

So, Larry, you say this book has been edited twice, once by the U.S. government, because there's 2,500, 2,600 redactions in here, and then a second time by yourself. And unlike any other book, you haven't been able to talk to the author, right?

LARRY SIEMS, Editor, "Guantanamo Diary": Right.
