I just received a copy of Seth Rosenfeld's "Subversives" -- a book about the early days of the student rebellion of the 60s. I've written about that era quite a few times, for the Free Speech Movement at UC Berkeley and the more or less general student rebellion it inspired were deeply influential to my own perspectives about American imperialism and authoritarianism. What I've written about it is almost all my personal perspective on events I witnessed (in person or on television) or was involved in (such as the Draft Moratorium protests in Oakland in 1967 -- I was there for my pre-induction physical.)
Rosenfeld got hundreds of thousands of documents that I understand revealed the deep, deep involvement of the then-existing Security State to infiltrate and disrupt the student rebellion, largely at the behest of J. Edgar Hoover, FBI Director since dirt was new. There was much more Security State involvement than we knew at the time, that's for sure. And yet the fall out from the events of those days -- including the apparent co-optation of such rebel lights as Todd Gitlin and Mark Rudd, both of whom I have had at least passing dealings with -- continues to resonate.
I'm sure I'll have more to write about those days once I've finished the book.
