On May 4, 1970, members of the Ohio National Guard fired upon unarmed students at Kent State University who were protesting the Vietnam War. Four students — Allison Krause, Jeffrey Miller, Sandra Scheuer, and William Schroeder — were killed, while nine more students were wounded. One of those wounded students, Dean Kahler, became permanently paralyzed.
In the aftermath of the shootings, sentiment against the Vietnam War and particularly the United States' invasion of Cambodia became heightened. Students protested throughout the United States, and a student strike of four million students led to the closing of more than 450 campuses.
The legal aftermath was complicated as well. In 2002, a guest named Stephen at the ANTIQUES ROADSHOW event in Cleveland brought in a formal apology document to the families of the slain and wounded students, from the governor of Ohio and the National Guardsmen who were involved. Stephen's father was a judge involved in the case, which went to the Supreme Court before returning to Stephen's father. Appraiser Selby Kiffer said that "we very seldom see something from such recent history that strikes such a chord."
