We have lost.

25. I was very young when Kent State happened. How did the

general public react?

I found this on the History channel website:

Aftermath of the Kent State Shooting
Following the shooting, the university was immediately ordered closed, and the campus remained shut down for some six weeks following the shootings.
Numerous investigatory commissions and court trials followed, during which members of the Ohio National Guard testified that they felt the need to discharge their weapons because they feared for their lives.
However, disagreements remain as to whether they were, in fact, under sufficient threat to use force.
In a civil suit filed by the injured Kent State students and their families, a settlement was reached in 1979 in which the Ohio National Guard agreed to pay those injured in the events of May 4, 1970 a total of $675,000.

I don’t recall hearing of massive protests in reaction to the students being killed, but it did change the way the National Guard is utilized in the United States. It changed because again - they screwed up and killed some white people that time.
