From the Introduction: "Law enforcement is one among several professions most at risk of workplace violence. The nature of the work--working late at night, patrolling high-crime areas, and interacting with unpredictable people--makes officers vulnerable to injuries perpetrated by the customers they serve. By definition, workplace violence is not limited to incidents committed by members of the public; it also includes violence between workers. Although open source data are difficult to find, anecdotal evidence suggests that law enforcement officers rarely turn their weapons on each other, in spite of the fact that personnel work in an intense, fast-paced, and armed environment. For this first report in the series, 'On the Right Track', researchers partnered with subject matter experts (SME) in law enforcement and asked them to share their opinions as to why worker-on-worker violence seems so rare in police departments, especially given the previously-noted risk factors. The purpose of this report is to identify best practices based on these discussions, and recommend potential prevention strategies that the Department of Defense (DoD) might want to consider for its own workforce and prioritize for additional research."
