A simple checklist, that is all it takes: a cluster randomized controlled field trial on improving the treatment of suspected terrorists by the police
Funder: University of CambridgeAbstract: 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 ânational securityâ 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 âprocedural justice checklistâ (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 Hedgesâ 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 = â 0.370 [â 0.259, â 0.482]). Conclusions: PJ checklists offer a simple, scalable means of improving how state agents interact with terrorism suspects. The police can use what is evidently a cost-effective tool to enhance legitimacy and cooperation with the police, even in a counterterrorism environment

Reducing Assaults Against Staff Using Body-Worn Cameras (BWCs) in Railway Stations
Workplace violence is a major health and safety phenomenon. We investigate whether body-worn cameras (BWCs) can achieve a cost-effective reduction of assaults. We conducted a randomized controlled trial with train stations exposed to the highest recorded assault rates against staff in England and Wales. Treatment members of staff were equipped with BWCs and control staff were unexposed to BWCs. Official records of assaults against treatment and control staff as well as against any employee at the station complexes are used as outcome measures. Results suggest 47% significant overall reduction in the odds of assaults against BWCs-equipped staff at treatment versus controls locationsâor approximately two versus four assaults, on average, per station. In addition, we found a 26% significant reduction in assaults against all employees in the treatment versus control station complexesâ9 versus 12 assaults, on average, per stationâsuggesting that BWCs have a spatial diffusion of benefits effects. We estimate that BWCs can reduce at least 3,000 working days per year lost because of physical violence at work. We conclude that BWCs provide substantial benefits for staff health and safety to those who are equipped with the devices as well as to staff in the vicinity of BWC-equipped employees
