Hans?Heinrich Jescheck, this multilingual volume presents the lectures delivered at the colloquium held in his honour on September 27?29, 2009. The contributions, which focus on the criminal law challenges facing today's global risk society, showcase the Europeanization of criminal law and the European Convention on Human Rights. Criminal law issues raised in the modern risk society are also addressed, as illustrated by analyses of elandestine surveillance measures and preventive detention of potential terrorist offenders. The papers cover European, German, and Turkish criminal law.
