On May 4, 1970, the Ohio National Guard opened fire on unarmed students at Kent State University during protests against the U.S. invasion of Cambodia. Four students — Jeffrey Miller, Allison Krause, William Schroeder, and Sandra Scheuer — were killed; nine others were wounded. The shootings triggered a nationwide student strike, closing hundreds of colleges and universities. No guardsmen were ever convicted. The event became a defining symbol of the era's political violence and government force against civilians.
No National Guardsmen were ever convicted or criminally punished for the Kent State shootings, though criminal charges were eventually brought forward. The complex legal aftermath unfolded across both state and federal courts over several years:
Exoneration: In 1970, a special Ohio state grand jury completely exonerated the National Guardsmen, concluding they fired in self-defense.
Reversal of Blame: Paradoxically, that same state grand jury indicted 25 other individuals—mostly students and protesters—for rioting and destruction of property. All of these charges were ultimately dropped or dismissed a year later due to a lack of evidence.
The Federal Level: The 1974 Trial
The Indictment: After heavy pressure from the victims' families, the U.S. Justice Department renewed its investigation. In early 1974, a federal grand jury indicted eight former Guardsmen.
The Charges: They were accused of violating the constitutional civil rights of the students by using excessive force.
The Acquittal: In November 1974, U.S. District Judge Frank Battisti dismissed the case mid-trial and ordered an acquittal for all eight men. The judge ruled that the prosecution failed to prove the specific legal threshold required: that the Guardsmen had a premeditated intent to deprive the students of their civil rights. He noted the Guard may not have been justified in shooting, but the criminal case simply didn't meet the federal statutory requirements.
