Globalization is a distinctive feature of our contemporary world: circulation, of both people and information, is one of the hallmarks of contemporaneity. The increasing accessibility of means of transport, the worldwide set of communication established through the internet, the relentless creation of global social networks: all these possibilities do provide people today with an unprecedented amount of freedom. Another hallmark of our contemporary world is a pronounced sensitivity to the need for security, a sensitivity that is propelled by globalization itself: the inhabitants of a globalized world are especially sensitive to the risks that an improper exercise of these freedoms may engender. Among these risks contemporary societies are particularly worried about terrorism. Terrorism indeed can take advantage of boundless spaces and information. This makes it necessary for political institutions to try to strike a fair balance between people’s freedom and their need for security. Against this background, the Jean Monnet Module will be aimed at analyzing the way in which the law of both the EU and the EU Member States do strike a balance between such important demands. This general topic will be tackled from three different perspectives: those of substantive criminal law, of criminal procedure, and of constitutional/public law. The distinctive feature of the Module lies in its adopting a peculiar perspective under which the well-plowed subject of the relationships between freedom and security is approached: the point of view of the relevance that both human mobility and the new media have to this relationship. The project aims at reaching the following two main goals: 1) fostering the process of adaptation of traditional Academic and Professional Legal curricula to new issues emerging from the globalization process 2) making academic teaching and learning experiences instrumental to anticipate, analyze and solve social, economic and political problems.
