Protest organizer Tom Hayden, furious over a brutal, unprovoked police attack on Rennie Davis, voiced the protesters' frustration and anticipated what would happen: "This city and the military machine it had aimed at us won't permit us to protest. . . . Therefore we must move out of this park in groups throughout the city and turn this excited, overheated military machine against itself. Let us make sure that if blood is going to flow, let it flow all over this city. If gas is going to be used, let that gas come down all over Chicago. . . . If we are going to be disrupted and violated, let this whole stinking city be disrupted and violated."
