Use of force by law enforcement officials, including police and correctional officers, is a highly important issue. Yet whilst the situations in which these officials use firearms, and the effects of this use, are relatively well documented and understood, this is not the case with 'less lethal' weapons and 'less lethal' force. (For the purposes of this project, less lethal force, or LLF, includes the use of restraints, empty hand techniques and less lethal weapons. The latter are weapons, such as the electric-shock Taser, pepper spray or batons, intended to subdue or incapacitate rather than cause serious harm or death). There is a recognition amongst academics and practitioners alike that this needs to change. Internationally, the current UN Special Rapporteur on Extrajudicial, Summary and Arbitrary Executions has expressed the need for more research into LLF, as has the UN Subcommittee for the Prevention of Torture. Nationally, a recent article in Forensic Science and Medical Pathology called for research into, and better reporting of, less lethal force in the UK, as did the Experts' Meeting on Taser the PI convened in 2015 with ESRC funds. The National Police Chief's Council (NPCC) and College of Policing have stressed the pressing need for research into LLF, and the Home Secretary has called for more information on police use of less lethal force and has launched a review into Use of Force Reporting (the 'Reporting Review'). At least three key topics around less lethal weapons remain under-researched, and this project will tackle all three directly. First we lack a basic understanding of when, why, on whom, and how often, less lethal weapons are used - and whether certain groups of people (those of a particular gender, ethnic minority, mental health status or geographical origin) are more or less likely to have less lethal force used on them. This project will see the PI work closely with the National Police Chief's Council, the Home Office and UK police forces, utilizing datasets previously unavailable to academic researchers to answer such questions. Such issues are also relevant internationally, as shown by recent debates on police less lethal force in countries as varied as Armenia, Hungary and New Zealand. Second, whilst these weapons are associated with saving lives, they have also been associated with serious injuries and fatalities. In the UK alone, several high profile deaths-including that of Ian Tomlinson and Jordan Begley-have occurred following police use of less lethal weapons. There are key questions around how so called less lethal force can impact the right to life, and their association with fatalities worldwide. Building on my PhD work focusing on injuries associated with Taser, this project will see the PI work with the UN Special Rapporteur to research the impact less lethal force has on the right to life in the UK and globally. Third, if it is important to attend to the situations in which force is used, it is also important to look at how such force is monitored and governed. This requires working with police and government to help understand what data on less lethal force should be gathered and analyzed, and working with the independent oversight bodies that monitor places of detention (including police custody) to ensure that they have the necessary research to enable them to document the LLF used by state authorities. The UN Subcommittee for the Prevention of Torture has highlighted the need for research to assist them in addressing and monitoring less lethal weapons and other physical infrastructure found in places of detention. The PI will work with key decision makers on these issues; with the UK government on reporting, and with oversight bodies via the SPT and its network of over 40 national bodies.
