A Farewell to Firearms? The logic of weapon selection in terrorism: the case of jihadist attacks in Europe

ABSTRACT In the vast literature on terrorism the choice of weapons has received relatively limited attention, despite the importance and visibility of this topic. Building on the literature on innovation in terrorism, the article first proposes a multi-level analytical framework that helps study terrorist weapon selection. It then investigates the use of weapons in jihadist attacks in Europe from 2014, with the rise of the so-called Islamic State, until 2020, based on an original database. The empirical analysis shows that the two traditional types of weapon of modern terrorism, firearms and explosives, were largely replaced by more primitive tools like melee weapons. In fact, in recent years jihadist terrorists in Europe have become less technologically advanced. Based on the original analytical framework, the article examines the reasons of this evolution, paying special attention to the use of the most common type of weapon in the database, bladed weapons, and the most lethal type, firearms.
