The protester is trying to protect himself by covering his head with his arms, curling into a ball, and rolling on the ground. The protester's black cowboy hat is lying in the middle of the street. Behind them, two cars (one is a VW Bug) are parked along the street. On the back of second photograph (H98.1.970) a description is written in black felt pen.

In order to show their opposition to the Vietnam war and the on-campus ROTC presence, protesters marched on California Hall, the location of the chancellor's office, and Callaghan Hall, location of the Naval ROTC's headquarters. Violence, including rock-throwing, erupted and police used tear gas to disperse the demonstrators. Members of the "Weathermen", a radical faction of the SDS (Students for a Democratic Society) were implicated in the organization of the protests.
