 "Frontline" executive producer Michael Sullivan said, "one should be cautious in ascribing its meaning.The photograph does give much support to the eyewitnesses who say they saw Ferrie and Oswald together in the C.A.P., and it makes Ferrie's denials that he ever knew Oswald less credible.But it does not prove that the two men were with each other in 1963, nor that they were involved in a conspiracy to kill the president."
