I don’t recall anyone saying that the Kent State Four “provoked” the attack.
It is the same as blaming a rape victim saying she was asking for it.
The National Guard shootings at Kent State were the result of a week of simmering and outright violence committed by a) leftist radicals who burned down the on campus ROTC Center and b) a wildcat Teamsters strike during which the guardsmen, most of who were about the same age as the KSU students, had spent 48 sleepless hours guarding truckers who were defying the strike and getting shot at from freeway overpasses.
On May 4 a group of screaming and rock throwing protestors pushed the guardsmen, sent on campus to prevent more riots and carrying bayonetted M1 Garands, down a hill. When the guardsmen fired they were shooting uphill and some of the bullets carried cross campus striking uninvolved students. So some of the "Four" were innocent bystanders and the whole incident was tragic.
But to say it was "unprovoked" is not exactly correct and in no way can one equate the guard and their actions with terrorists attempting to massacre dozens of people over an irreverent middle-finger-to-your-murdering-pedophile-false-prophet cartoon event.
Even though they did.
