"The last several decades have seen a downward trend of violence against law enforcement officers; however, the threat of on-the-job injury or death is still real for officers nationwide. For example, vehicular accidents remain a persistent and high cause of officer deaths, but 2016 saw a noticeable uptick in the number of firearms-related officer fatalities compared to recent years. [...] To help address these issues, the COPS [Community Oriented Policing Services] Office and BJA [Bureau of Justice Assistance] decided to focus the October 2016 OSW [Officer Safety and Wellness] Group meeting on how to develop and support resilient officers and agencies."
