I lived in Chicago and worked in the Loop starting in 1970. My job required that I wear a suit and I of course had short hair. The day of Kent State I believe it was May 7, I was on Michigan Avenue and kids from Roosevelt University poured onto the street. I had no idea what was up -- they were mad and in an uproar. They singled me out and a cop had to pull me away from the confrontation.
The cops took the brunt of the abuse -- they had sh** thrown at them and were spit at and pushed and shoved. The Democratic Convention riots of 1968 caused Chicago PD to very gentle with the protestors.

I remember watching these gentle police after Daley decided he had enough of the protesters. LOL, hit 'em again.....
