Could an incident like Kent State happen again?Not within conditions as they exist today. Campus violence is non-existent and public protests are, for the most part, peaceful. The one time that police acted involved only tear gas, and the action might not have been needed.
Plenty of analysis has been done on Kent State. What the incident involved was a bad combination of rowdy college kids facing an armed force that wasn't well trained in civilian crowd control. The force was armed for combat, not rocks and bottles. The government had a confrontational attitude toward the population. Things are different today.
For one thing, everyone has been cowed through economics. Nobody wants to rock the boat because unemployment doesn't have nearly the safety net it once had, keeping employment does not have much legal support, the cost of college is out the roof, and entry level positions for grads are hard to find. Joining the armed forces is a viable means to making a living.
Few people below the age of fifty were old enough to have a clue as to what was happening during that time. Those who were involved are heading toward retirement right quick. The white-hot anger that fueled Kent State and many other violent confrontations is gone. You know, there was serious concern about a violent revolution during the 1970s, not just the stupid things in That Seventies Show. Actually, it was from about 1966 to 1974. In 1975 the turn was made.
In all, violent confrontations with the military is now the provence of crazy right wing types who think that a few pop guns could possibly take on a sophisticated military force. Those types seem to be going away too. It could be that nobody wants violent confrontation.
As far as the current radicals go, they are pretty timid in comparison. There are no campus bombings, dramatic bank thefts, taking over campus buildings and the other messes that characterized the Kent State times.
The Internet has to be considered too. A lot of venting goes on in this medium, which serves to cool down hot heads. Communication goes on too, plus coordination, and it is now harder for truly twisted types to get a following.
Anyway, this subject is pretty big. A lot has happened over a couple of generations, and a lot more promises to happen. I don't think another Kent State will develop.
Heh, just saw the news report of Rumsfeld being confronted -- with words. And words from a retired CIA guy, not just emotional hecklers. Times, they have been and are a-changing.
Here's the Wik link to the history. Seems to be pretty well researched:
