You might be interested in this new development.
On 26/6 Miami Herald ran an article with the new FOIA/JFK act documents about Posada's ties to CIA, which his defense team hopes give him protection in the US on the ground he was an employee of the US government and thus can not be extradited for the Cubana flight bombing plot among other things.
Interestingly enough, they also cover the option whether he could have been part of the JFK assass. hit team etc.
Pretty interesting article for main stream media. Download their attachment with the declassified documents:
