Don't Forget Jack Rubenstein
Ruby was a mafia insider. The person assigned to eliminate the patsy was Officer J.D. Tippet, who failed to get Oswald in the immediate tumult. Three operatives, not Oswald, then took out Tippet (sp?) as planned to complete the wash. But Tippet’s failure left Oswald alive. Jack Rubenstein was the guarantor for the patsy operation. He knew what he had to do. How did he know? I’m not aware of those puzzle parts, but Rubenstein was a very familiar face among a DPD on the payolla.
