In his interview with Gil Toff in 1971 Jack Dougherty told Toff that he was alone in the Domino Room eating lunch while Oswald was up in the 2nd Floor Lunch room eating his lunch...
Truly helped destroy Dougherty's credibility by calling him retarded and defaming him as his supervisor and undermining his statements...
It seems obvious to me that the reason Truly did that is because Dougherty refused to go along with the framing of Oswald and told the truth that Oswald was up in the 2nd Floor Lunch Room in his interviews...And that was difficult to do damage control for by the conspirators and was resolved by destroying Dougherty's credibility...
Domino Room is out Zeon...And, if you recall, Lovelady said he looked in there before going out on the front steps with Shelley and Stanton...
