The Taliban is a radical group that used to control much of Afghanistan. After being routed early in the war, its forces remain a major obstacle to long-term security in the country. Jere Van Dyk of CBS News got an inside glimpse of this group the hard way – as a Taliban prisoner for more than 40 days. How was he abducted? What did he learn about the Taliban? And why did his captors let him go? Jere Van Dyk is here to tell his story, which is chronicled in the new book “Captive”.
