I see no contradiction in my post since my links showed the origins of the term/symbol. Nowhere was there a claim by me or evidence in the links about how well known/popular the understanding of its symbolism was in Dallas in 1963. I have no idea what the Birchers in Dallas knew about the umbrella symbol at that time. By the way, how many Bircher supporters were there in Dallas at that time? 50? 100? 1000? Was Witt a Bircher? He doesn't seem to have been one. Opposing JFK didn't mean you were a right wing nutjob Bircher, right?
The other links showed - the one by Charles and the one quoting LBJ - that it was known by some people in 1963. Probably more in Europe than the US. LBJ used it to attack Joe Kennedy Sr. and indirectly JFK. The liberal wing of the party was opposed to JFK's nomination. They thought he was too young, too close to McCarthy and that his father - that liberals greatly disliked - had too much influence over him. They particularly disliked him because of his support for appeasement of Hitler. Thus the LBJ quote.
As to Witt: Look, if you want to see a conspiracy behind his act then there's nothing I can do here to dissuade you. My experience reasoning with JFK conspiracy believers is not a good one. I don't know which side is to blame although I have a guess. Witt gave his explanation. You can interpret it as evidence that his act was sinister or that it was, as he said, embarrassing.

I'm not seeing a conspiracy behind his act. Earlier in the thread I posted this, mocking the idea the umbrella was a signal for an assassin:
"What is also laughable is the notion this is being used as a signal for a shooter (or shooters) to fire/continue firing. I can just imagine the meeting when that was arranged - "An umbrella? But what if it's sunny?"
When you posted the article about Chamberlain's connection with the umbrella and the term Umbrella Man, I was convinced you had made a sound argument for the possibility that Witt's claim might have some veracity. Hardly the approach of a run-of-the-mill CTer.
But I have had exactly the same problem you complain about - whenever I've tried to reason with LNers over various aspects of the case that are problematic for their narrative the experience has not been a good one. The usual tactic being the one you have just used yourself - dump me in with the more extreme CT views and move on.
But the issue is Witt's testimony.
It's not a question of my interpretation of what he is saying. His testimony is flatly contradicted by the photographic/film record - that is a fact.
Witt has his umbrella fully raised before JFK is hit by any shot (it is my personal belief, based on extensive research, that his umbrella is raised before the first shot is even fired).
He even claims to have seen the limo slow down and Hill running towards it. This is the moment JFK's head explodes but he somehow misses this little detail.
Witt is either lying, has a truly catastrophic memory or he wasn't there.
