While I don’t condone violent or offensive street actions, it should be recalled that the underlying reason for the ‘68 Chicago riots was Mayor Daley’s refusal to issue permits for rallies (through the legal process).
Instead, Daley relied on Chicago police to uphold orders (based on political posturing, rather than common sense), and some units went to the extreme of skull-cracking of innocents (McCarthy staffers) on an upstairs floor of the delegate’s hotel!
Do you think that we are seeing a potential return to that sort of thing because of the "free speech zones" the protesters are now often required to be in?
