Last year, 177 police officers lost their lives in the line of duty and 143 committed suicide. These deaths are devastating and unacceptable. The National Institute of Justice has developed a robust research portfolio to improve officer safety and wellness and, ultimately, save lives. The experts on this panel discussed some of the evidence-based practices and policies that law enforcement agencies can put into operation to reduce officer deaths and improve wellness and performance.


  • Bryan Vila, Professor, Washington State University, will discuss his work on officer fatigue.
  • Karen Amendola, Chief Operating Officer, Police Foundation, will discuss advantages and disadvantages of 8-, 10- and 12-hour shifts.
  • John Violanti, Research Professor, University at Buffalo, State University of New York, will discuss the long-term impact of police work, including suicide.
  • Theron Bowman, Chief of Police, Arlington, Texas, will comment on how police leaders can incorporate these research findings into their management and day-to-day work.
