CEP Strategic Advisor writes: "The rumblings began before the book was even published. When the book came out in January though, Bergeaud-Blackler, no stranger to sensitive subjects, could not have anticipated the response. The denunciations came thick and fast, some from Islamist sympathisers in the media and academic sphere, some from those who believed they were defending Muslims against a bigoted screed. The author’s conference at the Sorbonne was cancelled (since rescheduled) without a proper explanation. As the controversy grew, death threats arrived."

"Hans-Jakob Schindler of the Berlin-based Counter Extremism Project told the Bundestag that the dearth of information about the financing of Islamist groups in Germany is partly due to 'legal gaps and hurdles, existing limitations on the powers of the security authorities, as well as a lack of transparency requirements' for mosques and Islamic associations. He said that the legislative proposals could lead to 'major improvements' in filling the knowledge gap (Erkenntnislücke) about the financing of Islamism in Germany."
