Guantanamo Bay detainees have long been considered America's most dangerous enemies. So what happens when they walk free -- like the five detainees swapped for U.S. Army Sgt. Bowe Bergdahl? Do they return to terror activities or transition to quiet, private lives away from the mayhem? Well, it's a mixture of both. How dangerous is this latest swap? Mathematically, it's not an even swap. But President Barack Obama's administration maintains it's not a risky move for the United States. The five detainees have been at Guantanamo Bay in Cuba for years, and out of commission for a long time. They probably don't have extensive networks to tap into, according to two senior U.S. officials.
