(Of course, all of the above were decades ago, so we need to keep an open mind about the condition today in the respective countries.)
I'd say after those it was business and usual, and those involved didn't get even a slap on the wrist. If anything, venting through the press merely let people get steam out and forget more easily....
But we didn't get a repeat of either episode. That raises the possibility that people learned lessons, albeit imperfectly, from those experiences of others, which is something for which humankind (not uniquely among the species) has at least some talent.
That's a benefit of a free press. It can be aggravating to see some of the shadier so-called journalists go shamelessly whoring after eyeballs. Still, journalists' collective, competitive desire for attention helps to bring "training cases" (in NN terms) to a broader societal audience. That seems to influence at least some people's behavior. Over the long term — and not without exceptions, some catastrophic — that influence, on balance, is usually for the good.
And still, "twenty-eight guardsmen fired approximately 67 rounds over a period of 13 seconds" -- killing 4 and injuring many more.
Which begs the question, if there was major potentially elite affecting / government toppling issue instead of a small scale anti-war protest at a local university, what would be the response?
These what-ifs of history are certainly interesting though!
