Excellent comment Lela. Also the catalyst for the violence in Chicago in 1968 was the refusal by the democratic party to seat a black delegation on the floor of the convention. Some of the delegation were veterans. The pushing and shoving got started on the floor and then moved into the street, where it then exploded, becoming the huge riot. This was actually in a documentary I saw about the riots a number of years ago on PBS, I think it was on PBS.
