I caught that too, nice bit of revisionist wankery there. Daley sr was a Democrat - but he understood that a nutbar with a lit Molotov cocktail is a dangerous thing. I recall reading an account of the ‘68 convention written by a cop who was there. It was very, very much different than the Time-Life version everybody has been operating with.
Believe it or not, I was actually near rhe scene of that riot and saw it. My grandfather and I were coming home up Lake Shore Drive rom the Museum of Science and Industry.
Daley was a hero in my parents Democrat voting house.
