Law enforcement officers (LEOs) often bear witness to trauma in others, leaving them vulnerable to vicarious traumatization. Vicarious resilience can counterbalance the negative effects of trauma work and help individuals avoid vicarious traumatization. This study investigated the phenomenon of vicarious resilience in 10 LEOs. The research questions focused on how the LEOs experienced witnessing victims demonstrate resilience during adversity and how they themselves were impacted by that experience. A phenomenological methodology and semi-structured interviews were used to explore the participants' experiences. Constructivist self-development theory and vicarious resilience were the conceptual frameworks used to explain how LEOs experience vicarious trauma and vicarious resilience. Phenomenological analysis was used to organize the data and assist in the development of themes regarding the nature of the participants' lived experiences. Analysis of the LEOs interview transcriptions generated 19 themes; including LEOs feel encouraged from witnessing victims' determination to live in the face of death, LEOs are motivated to reevaluate their own adversities, LEOs feel inspired from witnessing and reflecting on victims' ability to survive trauma, and LEOs carry hope that future victims will be resilient. Overall, the findings indicated that LEOs experience positive experiences and personal growth from their work with resilient victims. Results of this study may be used in law enforcement training to stimulate positive social change that might improve the well-being of LEOs by providing awareness on how vicarious resilience can be used as a proactive measure in working with trauma victims.

The centrality of the police in everyday life means police officers are in position of power to actively support or threaten democratic activities (Sklansky, 2008) for example during protests. In democracies, policing duties should be performed in ways that sustain democratic values, rather than undermine them (Loader, 2006), yet that is not always the reality. Police training is one of the tools for aligning officers' behaviour with societal norms; it is considered a protection against the possibility that police officers abuse the wide-ranging powers they hold (Manning, 2010). Training programs are therefore a basic feature of all police forces' organizational approach. Despite its centrality, training has not received extensive academic attention; there is a pressing need to understand the impact of training on police behaviour and the mechanisms thorough which it operates (Skogan & Frydl, 2004). This thesis attempts to advance the evidence-base of democratic police training following the Medical Research Council's framework for the development and evaluation of complex social interventions (Craig et al., 2008). The Israeli Border Police was chosen as the context to examine the potential of training to advance democratic norms. The three stages of the research project included: theoretical modelling of the existing complex training intervention to assess its alignment with existing evidence; participatory development and piloting of a training curriculum on policing of protests in a democracy that used an Adult Education approach and introduced Procedural Justice-related components; and a pilot quasi-randomised study to evaluate this training. Analysis and reporting are carried out in a way that allows assessment of prospective scale-up and generalisability. Flowing from the empirical work, four strands of theoretical contributions are put forward. First, a theoretical model of police training is proposed, drawing on social psychology constructs. Second, contact theory, which originates in peace education, is proposed as a possible platform for designing both police training and their evaluation studies. Third, four factors limiting the efficacy of Procedural Justice & Legitimacy based training interventions in deeply divided societies are outlined. Fourth, the Border Police case study is used to substantiate the value of participatory research methods for advancing knowledge translation and evidence-based policing.
