If you watched the above film clip [only 6 min] you would be told that the Umbrella Man was supposedly protesting Nevile Chamberlain and [I guess] wanted JFK to feel his anger by raising it in front of him? The HSCA accepted this yarn. I find it difficult to because---He failed to come forward for over 12 years as a witness to a homicide...and his story reeks of more crapola than could be put in any umpty-hundred umbrellas. Photographs show that he sat down real cozy with another no show to the police...The Dark Complected Man and seemingly had a chit-chat apparently about the event that had unfolded. Some photos show that The DCM might have had a small walkie talkie in his hip pocket. At the passing limo [in the Zapruder film] ..the DCM is seen to lower his hand as one signaling to open fire.
Were they signal men? Nobody seemed to care.
