Profiling Violence Extremism and Radikalization

This dissertation addresses the assessment of threats posed by violent extremism and the process of radicalization, with a focus on the specific needs of security practice in the Czech Republic. Its primary objective was to develop a two-stage protocol, HRANA (Hybrid Risk Assessment and Analysis of Violence), designed to enable the efficient identification and evaluation of risk factors leading to extremist violence, particularly among lone actors. The methodology draws on a conceptual synthesis and adaptation of seven internationally recognized instruments for assessing the risk of violent behavior and integrates them within a Structured Professional Judgment (SPJ) framework. Findings indicate that effective detection of radicalization warning signs can be achieved through a multi-domain approach. The two-stage HRANA protocol (HRANA- Screen and HRANA-Core) demonstrates high content completeness and minimal item redundancy (! 10% by the Jaccard index). Compared with prevailing unstructured, subjective ad hoc judgments, the protocol provides more consistent and defensible decision support for security practitioners. An implementation analysis conducted in accordance with ISO 31000 classifies the overall risk of deployment as moderate. The dissertation makes a substantive contribution by bridging...
