Hans-Jakob Schindler, senior director of the Counter Extremism Project (CEP), notes that Islamist extremists are skilled at exploiting legal loopholes in Europe, citing imprisoned British Islamist preacher Anjem Choudary as a key example. “Anjem Choudary magically knew everyone who was a terrorist and going toward these groups in the U.K. over three decades. It took half a dozen attempts before the guy was actually in prison, because he was very smart in the way he formulated his messaging,” Schindler said, adding that Choudary “was very deliberate in how far he would take those contacts. He would radicalize the people, but once they became terrorists, they no longer had any contact with him.

CEP Strategic Advisor Liam Duffy writes: "The British public’s first real introduction to Anjem Choudary was as a supporting cast member in Jon Ronson’s 1997 documentary The Tottenham Ayatollah. The pioneering gonzo reporter closely followed the surreal day-to-day of Omar Bakri Muhammad, a Syrian-born former member of both the Muslim Brotherhood and Hizb ut-Tahrir who went on to found the more radical Salafi-jihadist activist network al-Muhajiroun (ALM)."

CEP Strategic Advisor Liam Duffy: "Yesterday, without ever having directed or plotted — much less committed — an act of violence, Anjem Choudary was jailed for a minimum of 28 years for terrorism offences. He was found guilty of continuing to direct the proscribed organisation, al-Muhajiroun (ALM)."

"Liam Duffy, strategic adviser at the Counter Extremism Project think tank, told The National Choudary had caused considerable harm and his fingerprints can be seen in terrorist groups across the world."
