I grew up 35 mi from Kent and saw it all.
The kids attacked the guard. It could have been much worse.
Kids were stockpiling dixiecups full uf redimix concrete and pelting the guard from dorm windows.
One of the dead girls was from 5 mi of my home.
We allowed the media to twist what happened in that incident and yes they won BIG.
That was prior to the internet
If I remember correctly, most of the victims were shot at extreme distance. I'll look it up and get back to you.
