Coauthor was Suwa; the theory in Against the State was about how violence may be necessary for democracy, sort of Jefferson's tree of liberty needing blood line.
I thought that was kind of interesting, whatever one's sympathies, but anyway the virtue of the book is that it is a first-rate decision-making narrative case study on the government side of the Narita story, as well as being surely the best thing in English (I wouldn't know about in Japanese) about what being a radical entailed.

Unless I have forgotten something of Ellis's many writings, the reference is to his book Japanese Radicals Revisited, which was about the 1960 crowd; he was revisiting them because Kazuko Tsurumi wrote a book about them earlier, if I remember correctly. He found the same people and wrote about their lives and views ten years after.
