My first thought is that I was very glad to see that there was no violence. In most Countries there would have been.
My second though was that when you design an education system to protect Government, and therefore educate students to a level where they believe that Government is there to wipe their ass every time they screw up, then when you confront those students as adults with any level of accountability, there will always be an obvious response.....usually involving one finger.
I wonder how many of them actually realize that they live in a Republic and not a Democracy......or maybe teaching them that would have confused the mesage.
