Filippo Spiezia, a great connoisseur of the subject, tells us all this and gives us a vivid portrait of transnational organized crime while suggesting the "recipes" to deal with it effectively. An impressive, precious work, which gives us the tools to face with awareness and lucidity the reality of our time and to move with a critical spirit within the enormous amount of information that causes us fears and insecurities. The former vice-president of Eurojust wrote the first Atlas of crime 2.0. Spiezia shows us how the different criminal organizations are articulated. All of them: those who are dedicated to more traditional activities (such as drug trafficking), and those destined for terrorist activities, which sow fear in Europe. His book makes us discover the contiguity between the mafias and the world of terrorism, and then let us understand that what we have in front of us are not two distinctly separate realities, but illegal structures that often compete in the same traffics and sometimes come to collaborate. Spezia's essay, at times as exciting as a thriller but always characterized by scientific rigor, is addressed not only to experts in the field but to a wider audience of ordinary citizens: those who do not have enough knowledge to give a precise face to what strikes their fear and who are therefore induced to react emotionally and irrationally. This is what happens after terrorist attacks like the one at the Bataclan in Paris, or when crossing an unsafe neighborhood, or when watching on television the continuous arrival of irregular immigrants on our shores. In Criminal Threats, Filippo Spiezia chooses the path of rationality and knowledge, instead of fixating on who shouts louder about the Islamization of our continent or the imminent ethnic replacement of the European population. His book gives us the exact terms of the problems facing today's societies, but it also points out the way to go to overcome them. It takes us to a rational terrain, the only one that allows us to act with concreteness and foresight. And he explains how illusory is to think that we would be able to return to "small homelands", when instead transnational mafias can be fought only with ever greater collaboration between European countries. Spiezia also demonstrates the importance of Eurojust in coordinating the investigations that are being carried out in each EU Member State; he tells us about the constant effort deployed in overcoming mutual mistrust and the profound differences between the various systems. But he also recognizes the limits that remain and that should be overcome. Despite his pro-European spirit, he does not ignore the issues: the author thinks, for example, that it was the inertia of the EU in facing the humanitarian emergencies that have broken out in Africa that offered to criminal organizations the opportunity to enrich themselves with trafficking in human beings. Spiezia remains aware of the many signs of progress that have been made, even while critically observing the non-fact and the long road that still has to be taken to counter the "crime 2.0" with an increasingly cohesive and up-to-date Europe. While speaking of the effectiveness of tools such as Eurojust and, more generally, of the need for collaboration between those who are committed to fighting against organized crime, the author finally underlines the importance of the insights of Giovanni Falcone, one of the firsts to understand the importance of judicial cooperation. Events proved him right. The fact that there are men ready to carry out his ideas gives us hope for the future. Maria Falcone
