Dunno... but I would bet that this would be fertile ground in which to hunt.
Archives at the UW and Evergreen, where they're actually proud of such things, are a good start. The Daily (UW student paper) is another place, along with the Seattle Weekly and The Rocket, both are "alternative" leftist papers. [alternative to what? Like the Seattle Times is a right-wing voice? bwaaahahah]
The UW paper (The Daily) had an archive I saw when I was a student there of the Fire-bombing of the ROTC building in the sixties. Some molotov cocktails were tossed through the windows and the ROTC building was gutted by the resulting fire.
The Daily dutifully reported it as the work of local "heroes". Frankly, I'm surprised that there isn't a memorial statue to them someplace on campus. But then again, this is the place where the main courtyard in the middle of the campus is still known as "Red Square".
Thanks for that info--sounds like some good leads.
