Mr. Glass, who was twenty at the time of the 1968 Democratic National Convention, grew up with a politically connected grandfather in Chicago's 24th ward. His grandfather arranged for Glass to be a greeter at the convention. He chose not to do this and instead went to the area around the Conrad Hilton Hotel. He was in the crowd as the mood intensified and the police presence grew increasingly violent. Glass described the situation as "an absolute free-for-all" involving tear gas, bayonets, and a sea of confusion.
