This BBC story looks at an attempt in Yemen to rearrange the thought processes of hardcore Islamist militants. Hint: It's not going so well.

An excerpt:

Doubts have been growing over the effectiveness of a pioneering Yemeni scheme to fight Islamist violence by using dialogue to convert extremist prisoners to more moderate views.  

Launched three years ago, the project has been followed with interest by British and other Western governments.

The Islamic scholar behind it, Judge Hamoud al-Hitar, has been invited to London twice to lecture senior anti-terrorism officers.

Muslim prisoners in London will now be given mentors before their release to help them understand mainstream Islamic values and prevent them being attracted to extremism.

But in Yemen, some say Judge Hitar's scheme - which the state claims has helped stop terror attacks there - is a sham and does not motivate any real conversions.  

There are even some reports that former al-Qaeda militants released by Judge Hitar have been caught fighting coalition forces in Iraq.

Osama Bin Laden's former bodyguard - previously paraded as one of the scheme's star pupils - has admitted his basic views have not changed at all, although he did say he has renounced all violence and would refuse to fight for al-Qaeda.
