Peace Officers Memorial Day and Police Week is an observance in the United States that pays tribute to the local, state, and federal peace officers who have died, or who have been disabled, in the line of duty. The Memorial takes place on May 15, and Police Week is the calendar week in which the Memorial falls. The event is sponsored by the National Fraternal Order of Police and is implemented by the National FOP Memorial Committee. Other events of National Police Week include the annual Blue Mass, Candlelight Vigil, Wreath Laying Ceremony, National Police Survivors Conference, Honor Guard Competition, and the Emerald Society & Pipe Band March and Service. The events draw 25,000 to 40,000 law enforcement officers and their families to Washington, D.C. every year.
