In which the Ohio National Guard killed 4 and wounded 9 unarmed students who were protesting escalation of the Vietnam war?
The Governor called 'em in. Now it would be handled by better trained SWAT units, presumably. As it was, turning ill-trained youngsters with loaded weapons on students was a nightmare.
President Nixon on down, it was a paranoid time for these war mongers, and their little citizen militia. No problem shooting their peers at all, and that's a history lesson for all those current paranoid gun nuts who think the 2nd Amendment is there to let them try to overthrow the government. GI Joe's got an itchy trigger finger.
