Regulating cyberspace through criminal law and sanctions: A US-EU comparison. A decade ago the founder of Electronic Frontier argued that we have to approach cyberspace with a settler's determination to civilize it as rapidly as possible. In this course we will look at one aspect of the efforts to regulate cyberspace which have emerged in the last several decades in the US, the EU and its member states: The use of criminal law and administrative sanctions in order to outlaw harmful or illicit uses of cyberspace. In a first step, we will compare the different regulatory approaches of the US and the EU memberstates. In a second step, we will analyze the effectiveness of criminal and administrative sanctions in an area in which the national legislature faces a tremendous loss of (boundary) control. In a last step, we will discuss the efforts of the US and the EU to police cyberspace through transnational cooperation.
