"Our objective in this project is to explore and compare relevant cultural phenomena and legal determinations of civil security across Europe, taking into account the existing significant differences between countries and regions. We start by creating a framework that can be used to carry out a comparative analysis. We develop definitions of security effectiveness and efficiency that can be put into practice with the available data and in the context of the widely varying security systems in Europe. We consider a representative sample of selected countries, embodying the diverse regional security architectures, with regard to the sharing of responsibilities between public and private bodies and the role that citizens and their awareness play in regional security architectures. We study how the identified differences affect the effectiveness and efficiency of different kinds of security systems in these countries and regions. We determine what works and what doesn’t work with regard to particular types of risks, crises and disasters, and countries and regions. Finally we give specific advice, based on consensually agreed upon objective indicators and analysis, about what changes or modifications might result in improvements to the security situation in regions or countries where this is desired by EU policymakers. Consequently, we achieve the expected impact of giving the EU a clear view of which kind of systems that could successfully enhance the security in certain regions, and contribute and give EU-added value to the debate concerning “not one security fits all”."
