Nobody in their right mind would believe that Walker was actively plotting to kill JFK 9 months before the event.
Well R.F.K had the headcase committed back in 1962 he sure had plenty of motive.
The issue that led to General Walker's resignation began in April 1961 when Overseas Weekly, a privately owned newspaper circulated among members of the armed forces overseas, accused the general of using an Army information program to subject his troops to "a propaganda barrage" that extolled the John Birch Society. General Walker was then commanding the 24th Infantry Division, based in West Germany.
The newspaper also reported that the general had publicly asserted that former President Harry S. Truman, Eleanor Roosevelt and former Secretary of State Dean Acheson were "definitely pink."
The report attracted widespread attention, and President Kennedy ordered an investigation into the matter. The general was relieved of his command while the inquiry was conducted.
In June 1961, the Army said the investigation showed that the general's information program was "not attributable to any program of the John Birch Society." But it admonished the general "for taking injudicious actions and for making derogatory public statements about prominent Americans."
He resigned on Nov. 2, 1961, contending that he "must be free from the power of little men who, in the name of my country, punish loyal service to it."
By resigning rather than retiring, he passed up retirement pay that at the time would have amounted to $12,000 a year. To accept retirement benefits, he said, "would be a compromise with my principles."
