McGrath,

Some of the students were just walking to class, not protesting at all, which makes it a little more complex. In fact, a lot of the students weren't protesting the war as much as they were the presense of the guard. And a large portion of the crowd was there just to watch.

To my mind this raises questions about agitated and confrontational protests and whether its OK to do something that might get a bystander killed (no matter what side of the confrontation you're on--protester or guardsman).
