I disagree. Read what Jose Lanuza told the Miami Herald in 2019:
Joannides would NOT have been approved to be the CIA’s liaison for the HSCA had Congress known his background at that time.
So, Lanuza believes some conspiracy stuff-fine. But notice he did not say "The DRE was running an Oswald Operation at the behest of GJ."
And GJ would not have been approved-so what? No evidence that he covered up anything, only that he didn't tell about his own operations likely because he didn't want to be interviewed by the committee. Also, the evidence that the HSCA was that interested in what the DRE and their 1963 case officer were doing is very slim. My article has already addressed Blakey and most everything said by Hardway is based off of him.
