As part of the 2004 Republican National Convention protests, United for Peace and Justice organized a mass march, one of the largest in U.S. history, in which protesters marched past Madison Square Garden, the site of the convention. The march included hundreds of separate contingents as well as individual marchers. The group One Thousand Coffins held a procession of one thousand full-scale flag-draped cardboard coffins, commemorating each of the U.S. fallen troops as of that date, carried by a nationwide coalition of citizens, veterans, clergy and families of the fallen. Several hundred members of Billionaires for Bush held a mock countermarch. Estimates of crowd size ranged from 120,000 (unnamed police spokesman) to over 500,000 (organizers, second unnamed police source). In March, 2007 NYPD Deputy Commissioner Paul Browne stated about the RNC protests: "You certainly had 800,000 on August 29th."
