"Firearms are one of the leading causes of deaths for law enforcement officers feloniously killed in the line of duty. According to data published by the Federal Bureau of Investigation (FBI), approximately 92% of the 535 non-federal law enforcement officers feloniously killed in the line of duty between 2003 and 2012 were killed by a firearm. Law enforcement officers who are shot in the torso are more likely to die as a result of their injury than if they are not wearing a vest. […] Congress is considering legislation that would reauthorize the program through FY2018. S. 933, the Bulletproof Vest Partnership Grant Program Reauthorization Act of 2013, would, among other things, reauthorize the BPV [Bulletproof Vest Partnership Initiative] program until FY2018. The bill was introduced on May 13, 2013, and was reported by the Senate Judiciary Committee on August, 1, 2013. This report provides an overview of the BPV program. It also provides a discussion of  data on law enforcement agencies that require their officers to wear armor vests while on duty,  research on why officers may choose to wear armor vests,  research on the life cycle for armor vests,  data on the use of body armor by law enforcement officers who were killed with a firearm, and  research on the effectiveness of armor vests. The report concludes with a survey of congressional issues policy makers might consider when debating legislation to reauthorize the BPV program."
