In the aftermath of the Paris terrorist attacks earlier this month, perpetrated in the name of Islam by three gunmen born and raised in France, there has been wide discussion in France about how hard-line Islamists succeed in enrolling a section of the country’s disenfranchised youths into their midst. Beyond the influence of extremist networks that operate in public places, notably a number of mosques, the role that prison plays in the recruitment of potential jihadists has been highlighted, notably by French Prime Minister Manuel Valls. Shortly after the attacks, he suggested that jailed radical Islamists may be grouped together in special quarters in prisons to limit their current opportunities of converting fellow prisoners to their cause. Mediapart’s Joseph Confavreux and Carine Fouteau sought out the opinion of Jean-Marie Delarue, who until July 2014 served for six years as France’s general inspector of prisons. In this interview he argues why he believes the proposition is misguided and potentially dangerous.
Protests continued on Saturday across many Muslim countries over Charlie Hebdo magazine's coverpage cartoon of the Prophet
The shooting attacks in Paris last week claimed the lives of a total of 17 victims and ended with the deaths of the three gunmen. The outrages, perpetrated by Islamic extremists and which began with the massacre at the offices of Charlie Hebdo magazine before the separate murders of two police officers and the executions of four hostages in a Jewish supermarket, have opened a vast societal debate in France. There have been comparisons made with the 9/11 attacks in the United States, questions raised about the true significance of the national unity displayed during last Sunday’s huge marches in defiance of terrorism, about the real extent of integration, and stigmatization, of the French Muslim population, and why the jihad increasingly lures some young French citizens. In this interview with Joseph Confavreux, Olivier Roy, a recognised expert in France and abroad on questions of Islam and religious fundamentalism, discusses these and related issues, and highlights the taboos that cloud an effective analysis of the events.
