Your faith in the integrity of CIA agents is something that I don't have.
I simply don't accept Bringuier's word as proof that Joannides wasn't involved.
The burden is on you and Fred to explain why the CIA went out of their way to lie and obstruct investigations into the matter.
Well, you reject the evidence and here we are. How do we disprove this? What would you accept? What did the other DRE people in New Orleans say? It's not just Bringuier. But if they say Joannides gave them no orders then you'd reject that too. You not only have the CIA behind it, you have private individuals involved.
The burden is on the people making a claim, Jon. Whether the claim is Oswald alone shot JFK or there was a conspiracy. It's up to the people making the argument to support it not others to disprove it.
