Zur Begründung der Hangtäterschaft gemäß § 66 StGB bei extremistisch motivierten Straftätern
摘要
Preventive detention (Section 66 of the German Criminal Code, StGB) is typically imposed following severe and repeated violent or sexual offenses; however, the legislature also recognizes ideological extremism as a potential basis for preventive detention and recently reaffirmed this with a change in law in 2017; however, the established criteria for assessing a propensity under Section 66 StGB, derived from general violent and sexual offending, are only partially applicable to extremist-motivated offenses. Often, these offenders appear in the criminal justice system for the first time, albeit in particularly severe cases; the existing catalogue of criteria does not capture the central motivational factor of radicalization. The article is based on all forensic psychiatric expert opinions and judgments of German higher regional courts from the past 10 years (date of query: June 2024) in which the imposition of preventive detention for extremist-motivated offenders was seriously considered. The expert opinions and judgments were made available to the authors by the Federal Prosecutor General at the Federal Court of Justice (GBA). In addition, an oral expert opinion from 2025 and 2 written forensic psychiatric opinions prepared by the author (J.F.) on behalf of the GBA, including their oral presentation and the associated judgments from 2025, were analyzed. Based on the identified expert and judicial argumentation structures, the article derives criteria that may serve as supraindividual indicators of so-called propensity to commit crimes under § 66StGB for extremist-motivated offenders. The findings show that ideological radicalization, combined with hostility towards enemy groups and a propensity for violence, represents a key perpetrator-related propensity criterion. Longitudinal and cross-sectional analyses can indicate that radicalization constitutes an “ingrained inner state” in the legal sense of propensity, even in first-time offenders. It also aligns with other propensity criteria established by Habermeyer and Saß (
