Every year since the memorial was first erected at the International Airport in 1977, officers from around the state have stood guard duty around the monument. Officers stand one hour of the vigil while a LEMA Honor Guard Officer walks the Thin Blue Line. This guard is changed every 20 minutes with a precision rifle inspection by the Sergeant of the Guard. An especially poignant point of the Memorial Guard involves canine officers with their partners sitting quietly in memory of the our fallen officers, and the several canines that have been lost on the job, many protecting the lives of their handlers. This event is held from 8:00 AM until 7:30 PM.
