1. Fundamentals: Theoretical Foundations and Doctrinal Structures

This project centres on the concept of ‘stochastic terrorism’, an under-examined yet growing threat to public security. As described by leading scholars, stochas­tic terrorism involves ‘the use of mass media to provoke random acts of ideolog­i­cally motivated violence that are statistically… more

This project deals with action-oriented measures of personal prevention in police law, which are linked to predic­tions that a particular person will behave unlaw­fully in the future. Such measures can be found in almost all areas of the special administrative law, ranging from reliability under… more

While civil disobedience is widely discussed in political theory, it remains mostly neglected in German legal schol­ar­ship. Bridging this gap, this dissertation examines under what conditions, and in what ways, civil disobedience may be constitutionally protected under German law. My primary… more

To limit the exercise of police powers, German public security law authorizes police to avert so-called dangers. That is, a ‘danger’ is a condition for legitimate use of police power. ‘Danger’ thereby is a term of art. Not all risks are ‘dan­gers’, and in the common doctrine, there is only a… more

Cyber attacks on government institutions and information technology systems occur regularly, representing a sub­stan­tial security threat to Germany and its economic and political interests. Besides passive defence measures, the so-called ‘hack back’ can be considered an active defence measure… more

In the quest for public security, communication is the most important operational resource used by police. When Ger­man police act in a preventive capacity, officers generally speak German while performing their duties. To over­come language barriers, the police may deviate from German, but there is… more

People with migrant backgrounds are strongly underrepresented in German policing. This fact is legally problem­atic for multiple reasons. First, due to violations of equality principles guaranteed in Art. 3 and Art. 33 II of the German Constitution. On an individual level, structures that discourage… more

A Critical Appraisal of Risk Assessment Structures of the European Court of Human Rights more

Risk assessment instruments provide a promising but controversial forecasting approach for security agencies. This doctoral project aims to structure the legal framework of their use in counterterrorism and counterextremism. A com­pre­hen­sive analytical framework will be developed by… more
