Discussion:
Richardson considered whether to use Oswald as a source of intelligence despite several official denials to the contrary and he was also managing other similar defector sources of intelligence that enhance the possibilities someone possibly decided to utilize Oswald for a related operation before the assassination of President Kennedy. Several Agency officials and Richardson himself would deny any inclination to use Oswald despite his own recorded considerations to the contrary. The House Select Committee on Assassinations was told by the Agency that his name was to be concealed even following the Select Committee investigation due to his continued work.
