Immediately before he argued that the controversy was over (with the qualifier that new evidence might emerge; thus the question mark at the end of the title), Epstein wrote something which would completely undermine the idea of closure:
"The lesson that Garrison has made abundantly clear is that the credibility of evidence cannot be divorced from the credibility of the investigator who presents it."
He underestimated how much the public would come to distrust the government as impartial investigator, that Vietnam and Watergate and the revelations of FBI and CIA abuses would essentially destroy that credibility, and that new opportunists building on Garrison would take advantage of that doubt.
It really does start with Garrison. It would have happened without him since there were other causes, the ones I mentioned above. And the questions Epstein raised in "Inquest" remained. But Garrison is the dividing line, the one between the responsible and irresponsible critics. Epstein thought that no line would emerge, that Garrison was completely discredited, and the country would move on. The fact that the Garrisonites still have any credibility is remarkable. Depressing but remarkable.
Still, what do we do with the Meaghers? She saw through Garrison, denounced him from beginning to end. And she still said that the WC was worse (!!?), that their investigation was more abusive and corrupt than Garrison's investigation. As I said, take away Garrison and something like him still comes about.
