Remembering the 9/11 attacks 25 years later

Today marks the 25th anniversary of the Sept. 11, 2001, attacks on the United States. We hear from a variety of voices remembering that day and its aftermath. A documentary photographer discusses one of her iconic photos. A former Guantanamo Bay prison detainee who was never charged talks about his experience. We highlight the profiles of victims who died at Ground Zero. Plus, a look at art and music that emerged in the years that followed.
