Tin soldiers and Nixon's comin'.
We're finally on our own.
This summer I hear the drummin'.
Four dead in Ohio.

Gotta get down to it.
Soldiers are gunning us down.
Should have been done long ago.
What if you knew her and
Found her dead on the ground?
How can you run when you know?

The Kent State shootings – also known as the May 4 massacre  or Kent State massacre – occurred at Kent State University in the city of Kent, Ohio, and involved the shooting of unarmed college students by members of the Ohio National Guard on Monday, May 4, 1970. The guardsmen fired 67 rounds over a period of 13 seconds, killing four students and wounding nine others, one of whom suffered permanent paralysis.

Some of the students who were shot had been protesting against the American invasion of Cambodia, which President Richard Nixon announced in a television address on April 30. Other students who were shot had been walking nearby or observing the protest from a distance ...

Eight of the guardsmen were indicted by a grand jury. The guardsmen claimed to have fired in self-defense, a claim which was generally accepted by the criminal justice system. In 1974 U.S. District Judge Frank Battisti dismissed charges against all eight on the basis that the prosecution's case was too weak to warrant a trial ...

KENT, Ohio -- A noisy, violent altercation and four pistol shots took place about 70 seconds before Ohio National Guardsmen opened fire on antiwar protesters at Kent State University, according to a new analysis of a 40-year-old audiotape of the event ...

"They got somebody," an observer says. "Kill him!" at least two male voices repeatedly shout, followed by sounds of a struggle and a female voice yelling, "Whack that [expletive]!" or "Hit that [expletive]!" Four distinct shots matching the acoustic signature of a .38-caliber revolver then ring out ...

The Kent State incident forced the National Guard to re-examine its methods of crowd control. The only equipment the Guardsmen had to disperse demonstrators that day were M1 Garand rifles loaded with .30-06 FMJ ammunition, 12 Ga. pump shotguns, and bayonets, and CS gas grenades. In the years that followed, the U.S. Army began developing less lethal means of dispersing demonstrators (such as rubber bullets), and changed its crowd control and riot tactics to attempt to avoid casualties amongst the demonstrators. Many of the crowd-control changes brought on by the Kent State events are used today by police and military forces in the United States when facing similar situations, such as the 1992 Los Angeles Riots and civil disorder during the aftermath of Hurricane Katrina in 2005.
