My copy of Josiah Thompson's new book, Last Second in Dallas, finally arrived from Amazon.
Glad to see he agrees with my views on Garrison (page 112):
There is another mention of Garrison on page 135:
"As for the assassination underground, what in the 1960s had been a selfless community of inquiry became in the 1970s a swamp of competing conspirÂacy theories and warring factions. Sylvia Meagher and I remained friends, but I drifted away from the others. The collapse of the Garrison prosecution of Clay Shaw had cast a deep shadow over the whole enterprise."
