As much as the law enforcement profession and its leaders strive to prevent the line-of-duty deaths of law enforcement officers, this worthy goal will never be fully achieved because the circumstances under which officers die are rarely within their control. The best that can be done is to sift through the details of how those officers who already made the ultimate sacrifice perished and to identify trends that will help prevent future losses of life. The Federal Bureau of Investigation’s (FBI’s) annual Law Enforcement Officers Killed and Assaulted (LEOKA) publication, from which most of the data herein are drawn, has contributed significantly to this commendable effort and remains a virtual treasure trove of vital information characterizing the myriad circumstances under which officers have died.
