In October of 1967, students at the University of Wisconsin Madison staged a massive protest against Dow Chemical Company recruiting on their campus. Dow made Napalm, the chemical gas that had become a symbol of the war in Vietnam. When students sat in at the Commerce Building, the university asked the police for help. As Madison police officer Keith Hackett recalls, “The university had wanted us to go in and, and clear the building, and they didn't say how. They just said, ‘We want them removed.’ And we said, ‘Fine.’”
