You may recall that Walker telephoned a newspaper editor in Germany about 18 hours after the murder of JFK, and told the editor (who was a personal friend of EAW) that Lee Oswald was the culprit who had tried to kill him in April.
This incident reveals that Walker was involved in the plot to murder JFK and he was desperate to pile as much derogatory
"evidence" as possible on the accused patsy, Lee Harrrrrvey Ossssswald ( Hisss Boooooo)
Walker was a key conspirator .....and you apparently believe he was an honest man of sterling character, and you believe everything he said.
