On May 10, 1972 3,000 people, mostly University of Minnesota students, protested the mining of North Vietnamese ports. Some tore down fences, flipping a car and coming into conflict with riot police at the scene. Susan Shroyer, who had been instrumental in the People’s Pantry, the predecessor to the Twin Cities’ first natural food co-op, was there with her 8mm camera, and she shared her dramatic footage with Radical Roots.
