Tribal elders, lower right, hold a ceremony before dismantling of the controversial sculpture "Scaffold" Friday, June 2, 2017 at the Walker Art Center in Minneapolis. Dismantling is expected to take four days and will be overseen by Dakota tribal elders. The Dakota people say "Scaffold", based in part of the design of the gallows used to execute 38 Dakota men in Mankato, Minn., in 1862, is not art and represents a painful history that Minnesotans have long ignored.
