Each year, hundreds of names of officers killed in the line of duty are engraved on the walls of the National Law Enforcement Officers Memorial in Washington, DC. These names are then read aloud during the annual Candlelight Vigil to memorialize those who made the ultimate sacrifice. The 36th Annual Candlelight Vigil was hosted on the National Mall in Washington, DC. Video from the event is available here: https://www.youtube.com/live/_AJEOg_3npQ Photos by Greg Torres/PPOA
