"May 4th is a particularly memorable day in American history because 84 years to the day before May 4, 1970, there was another demonstration at the Haymarket Square in Chicago"

The quote by William Kunstler highlights the historical significance of May 4th in American history by drawing a parallel between two distinct occasions separated by 84 years. Both occurrences include public presentations and unrest, showing the continuing battle for rights and justice.

The first event Kunstler referrals is the Haymarket Affair, which took place on May 4, 1886, in Chicago's Haymarket Square. The Haymarket Affair began as a serene rally in support of employees striking for an eight-hour workday. Nevertheless, it turned violent when someone threw a bomb at the police, resulting in the deaths of a number of policemans and civilians. The consequences caused a questionable trial where eight anarchists were founded guilty, and four were executed. The Haymarket Affair had a global impact, affecting labor motions and ultimately causing the establishment of International Workers' Day (May Day).

The second event pointed out is the Kent State shootings on May 4, 1970, at Kent State University in Ohio. This catastrophe happened amid the background of nationwide protests against the United States' intrusion of Cambodia during the Vietnam War. National Guard soldiers opened fire on unarmed student demonstrators, killing 4 and wounding nine others. The Kent State shootings ended up being a symbol of the tensions and departments within American society throughout the Vietnam War age, sparking widespread outrage and further protests across the country.

Kunstler's quote reflects on the styles of demonstration, state reaction, and the long-lasting fight for human rights and social justice in American history. By linking these 2 events, Kunstler emphasizes the cyclical nature of history where socio-political struggles and the mission for justice have actually been repeating elements. The remembrance of both May 4th occurrences serves as a reminder of the previous disputes while motivating reflection on the development and lessons learned from these historic moments.
