Fascinating, and eerie echoes.
Just five days after the shootings, 100,000 people demonstrated in Washington, D.C., against the war and the killing of unarmed student protesters. Ray Price, Nixon's chief speechwriter from 1969 to 1974, recalled the Washington demonstrations saying, "The city was an armed camp. The mobs were smashing windows, slashing tires, dragging parked cars into intersections, even throwing bedsprings off overpasses into the traffic down below. This was the quote, student protest. That's not student protest, that's civil war."[10] Not only was the President taken to Camp David for two days for his own protection, but Charles Colson (Counsel to President Nixon from 1969 to 1973) stated that the military was called up to protect the Nixon Administration from the angry students; he recalled that: "The 82nd Airborne was in the basement of the executive office building, so I went down just to talk to some of the guys and walk among them, and they're lying on the floor leaning on their packs and their helmets and their cartridge belts and their rifles cocked and you're thinking, 'This can't be the United States of America. This is not the greatest free democracy in the world. This is a nation at war with itself.'"[10]
President Nixon and his administration's public reaction to the shootings was perceived by many in the anti-war movement as callous. Then National Security Advisor Henry Kissinger said the President was "pretending indifference". Stanley Karnow noted in his Vietnam: A History that: "The [Nixon] administration initially reacted to this event with wanton insensitivity. Nixon's press secretary, Ron Ziegler, whose statements were carefully programmed, referred to the deaths as a reminder that 'when dissent turns to violence, it invites tragedy.'" Three days before the shootings, Nixon had talked of "bums" who were antiwar protestors on United States campuses,[49] to which the father of Allison Krause stated on national TV: "My child was not a bum."[50]
There's a lot more just about the aftermath:
