Remember when the authorities opened fire on students in May of 1970?

Ten days following the Kent State murders, the National Guard was deployed, but not allowed to carry ammunition. This time around, the state and local police opened fire: 140 shots into the crowd and the women's form. Every single window in the dorm was shattered. Two killed a dozen injured. No one was brought up on charges and a Federal investigation that authorities were not at fault. The FBI later concluded that there were no snipers, and no one fired at the police.

No one was convicted in the Kent State killings either.

I remember hearing about it at the time, but almost as an afterthought. I wondered why it didn’t get much attention.

It's true, this incident was never retold like Kent State.

I remember when that happened. I was in college.

Yes, I remember this, too. And it was the same year 8 black students at The University of Mississippi (Ole Miss) were arrested and suspended for protesting existing racist policies (in 2020, fifty years later, the school formally apologized).
