NOW on PBS partners with best-selling author and journalist Robert Lacey to investigate the surprising success of Saudi Arabia's approach to dealing with terrorists and extremists - without torture or water-boarding. Given extraordinary access to the Saudi Arabian Interior Ministry and its practices, Lacey visits terrorist rehabilitation camps that use "soft policing" tactics to be nice to the bad guys. In the program we see the Saudis providing a private jumbo jet to bring inmates home from Guantanamo Bay, giving them a hero's welcome, then sending them to a converted holiday resort for re-education. Then, the men are set free. Is this rehab program working, and can we trust the Saudis to protect themselves - and us - against Islamic extremism in the future? Watch this NOW on PBS report for a perspective on terrorism you've never seen before.
