Following the violent incidents in Aschaffenburg (2025), Mannheim (2025), and Magdeburg (2024), public debate increasingly revolved around the unclear motives and the mental health of the perpetrators. In all three cases, investigators from the security authorities found no clear motive, but did determine the presence of mental illness. In response, several political advances were made calling for the registration of individuals undergoing psychiatric treatment by security agencies and for an expansion of the “dangerous person”[i] (Gefährder) categories. Within research, diffuse motives for extremist violence and the role of mental health have been discussed for several years. However, the recent conflation of mental health and threat falls short of the complexity of the issue.
In the past three years, there has been a noticeable increase in public acts of violence in Germany. Whether they were driven by extremist motives has not always been clear. While some acts, such as the 2023 attack on a city festival in Solingen, could be assigned to a specific phenomenon area (in that case: Islamist terrorism), others, such as the Magdeburg attack of 2024, were more difficult to fit into established patterns. Moreover, it remained unclear what role the perpetrators’ mental health had played.
Unclear Motives, Mental Health, and the Role of Security Authorities
Political responses varied, but many linked motive and mental health, calling for more repressive security measures. For instance, following the attack on the Magdeburg Christmas market, members of the CDU/CSU parliamentary group demanded that violent offenders with mental illnesses be recorded by security authorities and that a new “dangerous person” category be introduced. The Conference of the German Ministers of the Interior also called for an “integrated risk management system for people with mental illnesses”. The Hessian state government recently came under pressure after introducing a controversial draft law to the state parliament that would amend the state’s Mental Health Support Act (Psychisch-Kranken-Hilfe-Gesetz, PsychKHG) by adding a clause requiring psychiatric institutions to share patient data with security authorities. The government defended the measure as a necessary contribution to the “protection of the affected individuals and the community”. Criticism of such initiatives came both from the general public and from professional associations. The German Chamber of Psychotherapists warned that such measures would “stigmatize people with mental illnesses and reduce the likelihood that individuals seek effective treatment.” During the hearing of the Health and Family Affairs Committee in the Hessian parliament, the planned reporting obligation was also met with widespread criticism.
From a scholarly perspective, these developments are noteworthy in that they mirror ongoing yet initially separate debates within extremism research. Central questions include how to classify motives and “dangerous persons,” how to account for mental health factors, and where to draw the boundaries and assign responsibilities for (preventive) measures. Two aspects are of particular importance here: the connection between psychiatric care and public security measures, and the expansion of the already ambiguous term “dangerous person” (Gefährder).
On the One Hand: Mental Health, Violence, and the Logic of Security Agencies
In the wake of attacks, public discourse often focuses not only on ideology and the attributed background of perpetrators but also on their mental health. Aspects of mental health also play a role for law enforcement when investigating motives and assessing criminal responsibility—which can, in turn, complicate categorization. Research broadly agrees that politically motivated violence cannot be explained by a single factor. Pathways into violence are complex and multifaceted; mental health may be one of many contributing components. Public acts of violence in particular highlight how closely society, politics, worldviews, and the psyche are intertwined.
This complexity, however, plays only a secondary role in the work of security authorities. Their task is to classify acts within established legal and phenomenological categories, with the primary aim of protecting public safety and order through risk prevention and law enforcement. This approach differs distinctly from that of psychological care, which centers on building a trusting therapeutic relationship grounded in respect and confidentiality. Psychotherapists and psychiatrists are bound primarily to the well-being of their patients and are subject to professional secrecy (§ 203 StGB, § 11(1) BO-H). Confidentiality, however, is limited when the safety of the patient or others is at risk. Therapists and psychiatrists are therefore legally required to disclose planned crimes or other threats to significant legal interests (§ 138 ff. StGB, § 11(2) BO-H). This safety mechanism is already well established in psychosocial practice.
Assigning psychiatrists a role in repressive threat prevention or granting security authorities access to patient data risks undermining the very principles of psychiatric and psychotherapeutic work. International research shows that the “securitization” of mental health can hinder the establishment of trust and deter individuals from seeking therapy. In addition, many places in Germany already lack the resources and capacity to provide comprehensive psychotherapeutic care. Instead of expanding psychosocial and psychiatric support systems for prevention and intervention, the political proposals discussed above would prioritize security logic and broaden the scope of state control.
On the Other Hand: Unclear Motives, “Potential Threats,” and New Categories
The second key aspect emerging from these debates concerns the categorization of attacks by security authorities. In the Magdeburg case, investigators reported no clear motive that would allow classification within the established spectrum of political violence. Although extremist and conspiratorial elements appeared in the perpetrator’s statements, investigators found no coherent ideological framework. The Federal Public Prosecutor’s Office therefore did not classify the attack as terrorism. Some scholars, however, have attributed a right-wing extremist ideology to the perpetrator.
Worldwide, an increasing number of politically motivated violent acts no longer fit the traditional typologies of extremism. The German Federal Criminal Police Office (BKA) recently reported that over a quarter of politically motivated crimes fall under the category “other classification.” The rigid categories of right-wing, left-wing, and religiously motivated violence have long been criticized. Moreover, there is a growing “hybridization” of ideological elements: perpetrators and their worldviews often combine disparate ideological fragments and resist clear classification. There is not yet a uniform term for these phenomena, given their diversity. While some scholars refer to “salad-bar extremism,” others emphasize recurring elements such as anti-feminist or antisemitic narratives and anti-governmentalism. Still others highlight the role of conspiracy theories and online subcultures of hate. These developments pose new challenges for intelligence and security services worldwide. In the UK, for instance, the national counterterrorism strategy has introduced the category “mixed, unclear, unstable,” and in Germany, the domestic intelligence agency (Verfassungsschutz) has added the classification “delegitimization of the state relevant to constitutional protection.” Such categorization efforts, however, remain diffuse while simultaneously expanding state intervention powers—leading to recurring criticism.
A similar issue arises with the term “dangerous person”, which featured prominently in post-Magdeburg debates. Since the early 2000s, it has gained increasing prominence in counterterrorism discourse and security practice in Germany, though it remains legally undefined. This ambiguity, combined with the far-reaching powers associated with such classification, has made the term controversial among scholars. The working definition used by security agencies in Germany refers to a persons for whom “specific facts justify the assumption that they will commit politically motivated crimes of considerable significance.” In contrast to convicted offenders, there has been no criminal offence committed yet), rather, it is a prognosis of future wrongdoing. However, in political discourse, the term has often been used as if it denoted certainty, particularly in connection with Islamist terrorism. Introducing a new “dangerous person” category based not on extremist affiliations but on an individual’s mental health would stretch the concept even further and make it prone to political exploitation.
The Need for Differentiation and Far-Sighted Responses
In the aftermath of recent attacks, political debates in Germany have blurred separate aspects: the hybridization of extremist phenomena and the role of mental health in violent acts. Conflating these aspects leads to a problematic simplification of causal relationships and overlooks the complexity of both radicalization processes and mental illness. The introduction of new, imprecise categories risks further eroding the boundaries between psychosocial care and repressive security measures. Public pressure on politicians after violent attacks is high, and the desire for public safety is understandable—but expanding security measures is not a panacea. Hasty demands for widened state competencies disregard the multifaceted causes of political violence and risk stigmatizing those with mental illness. In order to close security gaps, it is rather necessary to improve the psychosocial care and strengthen psychotherapeutic prevention approaches.
