NO>>>>>>>>>>>>>>it is NOT obvious that the OP was specifically talking about Race Riots that followed the assassination of MLK. In fact the OP NEVER used the term Race Riots. He used the term UNREST.
I remember the Watts Riots (saw coverage in LOOK, Life and Time magazines) I attended my first anti-Viet Nam War protest in 1967.
I was at The 1968 Democratic Convention in Chicago and experienced the terror of the Riots…Thank you Mayor Daley. Heroes of the Chicago Eight included Abbie Hoffman, Jerry Rubin, Tom Hayden, Bobby Seale (also tried in New Haven 1970 Black Panthers).
So, what may be obvious to you is not to me. I had far more political exposure in the 60s than you did (so it appears).
