Exactly, some of the nuttier nuts tend to hang their hats on loose nails.
As we've said before, you can't just strip out one interview or account and run with it. You have to weigh all of the other evidence.
William Manchester said that he interviewed Dave Powers, John Hagan and the two Gawler brothers, owners of the funeral home, in 1964 for his book. Powers noted his activities that day (11/22/63) and they show that he and the other WH staff, e.g., Lawrence O'Brien, picked out the casket that JFK was to be buried in from Gawlers at about midnight. Then he, Hagan, Gawler, and, from Power's note, their "young cosmetician" - I believe it was Thomas Robinson - left in the hearse with it headed to Bethesda soon after.
Again, that was around midnight.
So, did Robinson leave the autopsy, return to the funeral home, and then return to Bethesda with the casket? Or was he never there before arriving with the mortician team around midnight? Or was Powers referring to someone else?
