Following up on the Charles Drago "Doppelganger Gambit " -
Dallas, Texas. November 22, 1963. On the corner of Main and Houston, at 12:30 are these two interesting gentlemen:
It's been speculated the pair is William "Rip" Robertson and John Adrian O'Hare.
I found this info on the duo on another site:
William 'Rip' Robertson served in the Marines during WW2 before joining the CIA. He was heavily involved in the overthrow of the Guatemalan government led by Jacob Arbenz, and commanded the ship Barbara J during the Bay of Pigs invasion. In the summer of 1963, Robertson was the CIA officer present on the Eddie Bayo, William Pawley led mission into Cuba known as Operation Tilt. Robertson was also on staff at JM/WAVE headquarters in Miami. Close associates of Robertson's were John Roselli and David Morales.
John Adrian O'Hare is a mysterious character whose true alliances remain somewhat of a mystery. He was military intelligence aide to Douglas MacArthur's army intelligence team during the Korean War. O'Hare also served under Charles Willoughby. He was involved with the original planning and training of Operation 40 personnel and was closely connected to several Cuban militants including Rolando Masferrer. Other names used by O'Hare included Col. William Bishop, Col. Richard Gray, P. Harrison and Oscar del Valle Garcia.
