@Setanta,
I remember how that story was spin at the time but then and now it seem a clear case of young untrained troops facing an out of control "mob".
My university bowed down to the "correct" political views of these sad events and decided to shut down the university down for a day.
The students of the engineering school told the University that we either wish for classes that day or pro-rated refund on our tuition.
We was told that anyone in the engineering school that wish to do so including the instructors was free to do so under a voluntary bases.
Every one of the instructors and at least the norm number of students show up for classes that day in the school of engineering.
We was not at all that popular and ways of annoying us was found such as the cutting off of students funds for our magazine however no one attempted to beat us up.
Guess they fear that we would used the slide rulers that we all carry on our belts as a weapon.
