August 25, 2017 GPA 30-17 SECRET SERVICE TO TEST GUNSHOT DETECTION SYSTEM (WASHINGTON, D.C.) – The United States Secret Service has a no fail mission that requires the constant assessment of how we can effectively evaluate threats and mitigate vulnerabilities. In an effort to enhance situational awareness capabilities around protected fixed sites in Washington, D.C. the U.S. Secret Service will conduct a live fire calibration of a system that provides real time detection and geolocation of gunshots fired within proximity of protected sites. This calibration will occur on Saturday, Aug. 26, and will extend into the early morning hours of Sunday, Aug. 27. This testing is being conducted in cooperation with our law enforcement partners within Washington, D.C. The live fire exercise will consist of a series of ammunition rounds being fired into a Secret Service tested and validated bullet trap. Multiple rounds will be fired from various weapon systems in three shot increments which will create a multiple gunshot event. The exercise will be conducted within proximity of two Secret Service protected fixed sites. The following closures will be in effect during the live fire calibration:      Constitution Avenue closed from 15th Street to 17th Street, NW 15th Street, NW closed from Pennsylvania Ave and Constitution Ave 17th Street, NW closed from Constitution Ave and E Street north and New York Ave south E St NW closed from 15th Street to 17th Street Observatory Circle closed from Massachusetts Ave to the South Gate of the Naval Observatory The use of this system is a valuable tool to our protective mission. ###
