Only 41 "war on terror" captives remain at the prison camps on the U.S. navy base in Guantanamo Bay, Cuba. Roughly a third of them are being held there at Camp 7, a lockup so secret that its very location is classified. Known as "high value detainees." they all underwent brutal interrogations in secret CIA prisons elsewhere. Now a military judge is letting some of their lawyers visit Camp 7 for the first, and possibly only, time.
