'About 500 participants joined the rally in Washington DC. Some of the participants were at the White House, most at Lafayette Park. There was no confrontation with the four police departments sending minimal staff. Guy Fawkes masks were common though U.S. Park Police said they would not permit and would enforce that no sales be made in the park.' Photograph: jxfarmer/GuardianWitness
