According to william cooper. The umbrella man at deely plaza symbolized either when he opened the umbrella or the motorcade passed the umbrella man. In symbolism that meant JFK was not allowed to leave the plaza alive. The umbrella in masonic means that the masons must kill the profane. I think that is why it is bad luck to open an umbrella inside it confuses masons who think they have to zombie walk towards the nearest profane. So if a profane has interlopen upon a masonic act in say the woods. The umbrella man would signal when the cultists dash at you with daggers. Now i am paraphrasing that its from memory and it was not from the hour of the time episodes that featured the jfk conspiracy though it might be in there aswell. Pic related was a masonic illustration notice the umbrella.
