Extension of Langman's psychological theory of school shooters.
Kasalová, Petra ; Heider, David (advisor) ; Frombergerová, Anna (referee)
This bachelor thesis deals with the topic of school shootings. It is based on psychologically oriented research studies focused on the shooter's personality, especially on the theory of Peter Langman. The first part of thesis, among other school shooting theories, describes and discusses in detail Langman's categorization system. The next part focuses on the analysis of five shooters after 2011, specifically John Zawahri, Jessie Osborne, Nikolas Cruz, Bryan Oliver and Robert Gladden. In addition, these cases are divided into attacks in which killing took place and attempted attacks in which no one was killed. Research questions concern the applicability of post-2011 cases to Langman's categorization and the differences between deadly and attempted attacks. The results of the thesis confirm the applicability of Langman's theory to the five early mentioned cases after 2011 and offer the possibility of a minor extension of the theory. KEYWORDS school shooting, Peter Langman, mass shooting, attempted school shooting
