Analysis of incidents over the past ten years in Germany reveals that the boundaries between targeted attacks in schools and terrorist attacks are starting to blur. Bockler, Leuschner, Roth, Zick, and Scheithauer (2018) recently presented a set of hypotheses about similarities between the developmental pathways of school attackers and lone actor terrorists. To date there is only a small body of empirical research comparing these two forms of targeted violence in depth. In order to fill this gap, this article presents findings from a qualitative analysis of prosecution files comparing the developmental pathways of German school attackers (N = 7; age range: 13 to 23) and Jihadi attackers (N = 7; age range: 21 to 28 years) who committed their attacks between 2000 and 2013. Using theoretical coding and constant case comparison, the contribution shows that the two phenomena have overlaps in which developmental processes and social mechanisms are similar. Both school attackers and Jihadi attackers frame their act of violence using cultural scripts and perform the attack on a public stage where victims are attacked not on the basis of personal conflicts but because of their symbolic meaning. Taking into account the similarities in the perpetrators' developmental pathways, the authors propose that it might be more fruitful from an operational perspective to discuss severe target school violence and terrorist attacks under a common concept of demonstrative violence than to artificially assign them to exclusive classes of violence.
