WASHINGTON (AP) -- Tens of thousands of police officers from around the country are in Washington this week as part of National Police Week.
Attorney General Eric Holder is scheduled to give the keynote address at a candlelight vigil on Monday night.
Other events this week include a conference for family members of officers who have died in the line of duty, an honor guard competition and a memorial service.
The memorial service, which recognizes fallen police officers, began in 1982.
Between 25,000 and 40,000 people attend the events each year.
