Buckingham was ON the board. The DI contacted him cold. In his deposition he says he'd never heard of the DI before they contacted him. Again, he could be lying.
What references have you provided?
The article you dismiss, the one that shows the document was secret.
You have to be a little loony. You did not say "Buckingham". You did not say "contacted". You said "talks" and "board". Once more, we are discussing this whole topic because you claim that Dover is the same thing as Scopes in relation to a conspiracy. If that is true then a floating log is the same thing as the "Queen Mary" in relation to a luxury liner.
The article you dismiss, the one that shows the document was secret.
Well I showed you the document which doesn't have the markings which are claimed. So find one that has the markings you claim. Until such time as you provide the evidence, you are blowing smoke.
