A short article by Shiraz Maher on the Saudi Arabian prison de-radicalisation programme: http://online.wsj.com/article/SB1000..._LEFTTopBucket

Starts with:
It is now clear that the failed terrorist attack by Umar Farouk Abdulmutallab on Christmas Day was directed by al Qaeda in the Arabian Peninsula (AQAP). The reasons for the sudden resurgence of this previously almost extinct chapter of the global jihad network lie not in Yemen, though—where AQAP is based—but across the border in Saudi Arabia.
Ends with:
Omar Ashour, an expert on deradicalization programs at Exeter University, thinks this approach will ultimately result in more recidivism. "The Egyptians tried something similar in the 1970s and failed," he says. "The Saudi program is not comprehensive because it doesn't address the wider issue of religious and ideological reformation. While it doesn't do that, it can only offer a temporary panacea."

It appears that as long as the Saudis fail to address the regressive literalism and intolerance of their own state religion—which fuels radical Islam around the world—they will also fail to rehabilitate true jihadis.

An interesting balance to Christopher Boucek's longer period of work on the issue cited earlier.
