The CIA reportedly trained some enemy combatants from Guantanamo Bay to operate as double agents and traded them freedom for assisting US intelligence. After being trained in a secret facility known as "Penny Lane" and funded with millions of US dollars, some former prisoners succeeded in helping take down al-Qaeda leaders while others vanished without a trace.
Al-Qaeda has now welcomed al-Shabab--the group responsible for the Kenya mall attack--into its ranks. Despite targeted US killing of al-Qaeda leaders, more and more terrorist groups are joining the al-Qaeda network and expanding membership - what led former Australian intelligence analyst Leah Farrell to say, "al-Qaeda's bigger now than it ever has been."
Americans will never forget.
