This is just one of the infuriating details from that New York Times story:

“Moroccan authorities, for example, are seeking the return of Mohammed el-Guerbozi, a battle-hardened veteran of Afghanistan who they say planned the May 2003 attacks in Casablanca, which killed 45 people. He has also been identified as a founder of the Moroccan Combatant Islamic Group, cited by the United Nations as a terrorist network connected to Al Qaeda. An operative in that group, Noureddine Nifa, told investigators that the organization had sleeper cells prepared to mount synchronized bombings in Britain, France, Italy, Belgium and Canada. In an interview last year, Gen. Hamidou Laanigri, Morocco’s chief of security, said Osama bin Laden authorized Mr. Guerbozi to open a training camp for Moroccans in Afghanistan in the beginning of 2001. Last December, Mr. Guerbozi was convicted in absentia in Morocco for his involvement in the Casablanca attacks and sentenced to 20 years.

But the British government has no extradition treaty with Morocco and has refused to extradite Mr. Guerbozi, a father of six who lives in a rundown apartment in north London. British officials say there is not enough evidence to arrest him, General Laanigri said.”
