Doug - thanks for pursuing this issue. My point would be that "students don't get overt extra credit for protesting..."
There is no way that anyone can be certain that a subversive professor doesn't have a secret agreement with one or more of these scruffy unwashed students that amounts to a bonus for protest.
After all, this is Evergreen College - the institution that invited cop-killer Mumia Abu-Jamal to speak at graduation.
Actually this is a "riot" not a protest. It should be treated as such by the police and the FBI.
I posted the Mumia graduation story - http://www.freerepublic.com/focus/f-news/1925922/posts
And sent Rachel Corrie to her death. If there was ever a "college" that needed to close, it's this one.
