Many of those communities have never recovered to this day from the massive loss of businesses and jobs.
Then came the next great shock of 1968: The assassination of Robert F. Kennedy. Deep thinkers tried to claim that somehow it was America that was in some way responsible for these assassinations. In reality, the assassin of Robert Kennedy was not an American, but an Iranian.
Dispersed among these national shocks were various local and regional shocks, as colleges and universities across the country were hit by student disruptions and violence of one sort or another over one issue or another.
Like the ghetto riots, campus riots flourished where the authorities failed to use their authority to preserve order. Instead, academics sought to cleverly finesse the issues with negotiations, concessions and mealy-mouthed expressions of "understanding" of the concerns raised by campus rioters.
Many academics congratulated themselves on the eventual restoration of calm to campuses in the 1970s. But it was the calm of surrender. The terms of surrender included creation of whole departments devoted to ideological indoctrination.
Members of such departments spearheaded the campus lynch mob atmosphere during the Duke University "rape" case, as they have poisoned other campuses in other ways, all across the country.
1968 indeed left a legacy.
