The 67 shots that rang out at Kent State amid a May 4,1970 Vietnam War protest, killing four students and wounding nine, reverberate more than 50 years later. Many historians see the shootings as the moment America turned against the war. An audio play, drawn from the “Kent State Shootings: Oral Histories,” contains accounts from protesters, National Guardsmen, students, faculty and townspeople, brought to life by actors including Ron West, Steve Byrne and Tina Fey.
