On May 4th four students are killed by National Guard troops at Kent State in Ohio.
Killed: Jeffrey Miller, Allison Krause, William Schroeder, and Sandra Scheuer.
Wounded: Joseph Lewis, John Cleary, Thomas Grace, Alan Michael Canfora, Dean Kahler, Douglas Wrentmore, James Russell, Robert Stamps and Donald MacKenzie.
On May 15 two students were killed by state highway patrolmen at Jackson State in Mississippi.
Killed: Phillip Gibbs and James Earl Green.
The details are from Wikipedia. It must be noted that there is little mention anywhere about the Jackson State shootings. I remember vividly each of these days. I was a junior in college and we faced armed State Police in our protests. The students killed at Kent State were white and those at Jackson State black.
Each May 4th I wake and remember. It isn't just a Crosby, Stills, Nash & Young song to me. White students learned a lesson that black students already knew, the Establishment kills.
