People gathered at Halley Park for the "Fourth of You Lie" protest and march, hosted by the NDN Collective. Then they marched down Saint Joseph Street, chanting and singing. Organizers said the event was created to protest the Fourth of July and colonization along with police misconduct and brutality.

Candi Brings Plenty, Indigenous justice organizer for the American Civil Liberties Union of South Dakota, read a list of demands protesters wanted to see fulfilled at the beginning of the march. “Today has always been an open wound…because today is not the celebration of the Declaration of Independence. Because we are those merciless savages they warned you about," Brings Plenty said.

When the group reached Fifth Street, a smaller group broke off from the planned route and headed toward Dakota Mill and Grain. Four people then climbed the Dakota Mill and Grain Silo in downtown Rapid City and hung an upside-down American flag with the words “Land Back” on Sunday, July 4, 2021, in Rapid City, S.D.

The rest of the demonstrators joined the others at Dakota Mill and Grain where they were met with a line of South Dakota Highway Patrol troopers who threatened to protestors if they stepped onto Dakota Mill and Grain’s property.
