LA English YR 2023 UL https://krimdok.uni-tuebingen.de/Record/1869091442 AB Lone-actor terrorists have increasingly attracted the attention of researchers, policymakers, and practitioners alike. Despite this enhanced interest, few studies have compared the outcomes of lone-actor terrorist attacks with other terrorists, and those that have do not consider the terrorists? intention to kill in an attack. This study utilizes a sample of 230 terrorist homicide incidents from the Extremist Crime Database to examine the extent to which lone-actors perpetrate more severe attacks than other terrorists.
