“…This pattern was also observed by Hasisi et al when examining spatial characteristics of 71 vehicular attacks by lone-actor terrorists between 2000 and 2017 in Israel. 150 In contrast, when comparing residence-toattack journeys of lone actors versus group actors in a sample of 267 U.S. terrorists, Smith et al found lone actors on average travelled almost three times further. 151 To summarise, lone-actor terrorists have generally been found to engage in lengthy attack planning, with longer life spans as terrorists than group-based actors.…”

A systematic review of the empirical literature on lone-actor terrorism, the first of its kind, is presented. Across 109 sources, ten main themes that characterise this domain are identified and described: definitions of lone-actor terrorism and typologies; heterogeneity of lone-actor terrorists; presence of mental health issues and/or personality disorders; similarities with other lone-offender criminal types; motivation to act driven by personal and ideological influences; increasing prominence of internet use; ties with other extremists, groups or wider movements; processes of attack planning and preparation; role of opportunity/triggers; and a tendency towards leakage/attack signalling.

“…This has been the case with ISIS fighters who spent time in Syria and Iraq and are now returning to their home countries (Byman 2015). More broadly, the fact that some terrorists travel intercontinentally suggests that spatial clustering is modus operandi-specific (see Hasisi et al 2019), indicating a wider range of terrorism threats and responses.…”

A simple checklist, that is all it takes: a cluster randomized controlled field trial on improving the treatment of suspected terrorists by the police

Objectives When it comes to interviewing suspected terrorists, global evidence points to harsh interrogation procedures, despite the likelihood of false positives. How can the state maintain an effective counterterrorism policy while simultaneously protecting civil rights? Until now, the shroud of secrecy of "national security" practices has thwarted attempts by researchers to test apparatuses that engender fair interrogation procedures. The present study aims to test one approach: the use of a "procedural justice checklist" (PJ Checklist) in interviews of suspected terrorists by counterterrorism police officers in port settings. Methods Using a clustered randomized controlled field test in a European democracy, we measure the effect of implementing Procedural Justice (PJ) Checklists in counterterrorism police settings. With 65 teams of officers randomly-assigned into treatment and control conditions, we compare post-interrogation surveys of suspects (n = 1418) on perceptions of legitimacy; obligations to obey the law; willingness to cooperate with the police; effectiveness of counterterrorism measures; distributive justice; feelings of social resistance to the state; and PJ. A series of multi-level linear, logistic, and ordered logit regression models are used to estimate the treatment effect, with Hedges' g and odds ratios used for effect sizes. Results When compared with control conditions, implementing a policy of PJ Checklist causes statistically significant and large enhancement in all measured dimensions, including the willingness of suspects to obey the law (g = 1.022 [0.905, 1.138]), to cooperate with the police (g = 1.118 [0.999, 1.238]), distributive justice (g = 0.993 [0.880, 1.106]), effectiveness (g = 1.077 [0.959, 1.195]), procedural justice (g = 1.044 [0.930, 1.158]), and feelings of resistance towards the state (g = − 0.370 [− 0.259, − 0.482]).

“…Thus, it is in this context—that the police is a principal agent of both crime and terrorism prevention (Newman & Clarke, 2008; Perliger, Hasisi, & Pedahzur, 2009; Perry, 2014; Perry, Apel, Newman, & Clarke, 2017; Weisburd, Jonathan, & Perry, 2009) and a spatial‐temporal clustering of crime and terrorism exists—that there lies another possible substantive application of crime prevention to counterterrorism. Recognizing these parallels, crime scholars suggest that hot‐spots policing may be a relevant focused crime prevention program for effectively reducing terrorism on micro‐ and macro‐geographic units (Hasisi, Perry, Ilan, & Wolfowicz, 2019; Lum & Koper, 2011; Perry, 2019; Yang & Jen, 2018).…”

Research Summary: This study assesses the impact of state repressive counterterrorism actions on terrorists' targeting and lethality of the terrorism landscape in Israel.Using systematic data on government responses to terrorism and an empirical model that addresses reciprocal relationships, we analyze dynamical interactions between types of government repression with attacks against civilian or government targets, and deadly terrorist violence. Contrary to public policy pronouncements of forcefully fighting terrorism to eradicate terrorist threats, our results suggest that repressive counterterrorism actions by the state increase terror and deadly violence. Importantly, the results indicate that these unintended escalatory or backlash effects are dependent on the scope of government repression, the type of terrorist targets, and the lethality of terrorism.Policy Implications: Our findings provide insight into particular behaviors and exchanges within the state repressionterrorism nexus that evoke and prolong terrorist violence.Centered on key aspects of terrorist activities involving target choice and deadly violence, our ecological study contributes to the development of a systematic understanding of specific impacts of government policies on terrorism. In all, constructing an empirically rigorous evidence base for Criminology & Public Policy. 2020;19:483-514. wileyonlinelibrary.com/journal/capp
