Jamal Al-Harith, aka Ronald Fiddler, a convert to Islam, was one of the left's terrorist heroes. A Gitmo prisoner, the left vocally agitated on his behalf.
The Center for Constitutional Rights represented him, along with three other Gitmoites, in Rasul v. Rumsfeld. "The detainees at Guantanamo have been subject to deliberate humiliation because of the Defense Department's misguided and illegal effort to exploit their faith to break them down psychologically," said Eric Lewis of Baach Robinson & Lewis,
Their left-wing lawyers insisted that, "None of the four had ever been a member of a terrorist group or taken up arms against the United States."
The Guardian defended him, retold his sob stories of being tortured and claimed that he was not a terrorist in any way.
Al-Harith left the UK to join ISIS, after the United States foolishly returned him to the UK, and blew himself up. By then he was calling himself Abu-Zakariya al-Britani. His likely victims would have been other Muslims.
Their families can thank the Guardian, the Center for Constitutional Rights. Al-Harith's defenders did their job. Then he did his.
