Ive read his main body of evidence, he has about 100 ex-government witnesses, some of them hold very impressive positions of rank. Every witness statement is acompanied with the name and position of the person that made the statement. There are also many declassified documents that are supplied.
The thing about Greer's evidence is it stands on it's own merits, if any of his witnesses had been misquoted or Greer had simply fabricated these statements, it wouldnt take long for one of his witnesses to speak out or atempt to sue him. But none of this has happened. I think we can assume that the witnesses are genuine, could the witnesses be lying? its doubtful but its possible, but thats not something that can attributed to Greer.
Id like you to define 'credibility' what actually makes a person credible?
Credibility is a very illusive and illusionary thing to my mind.
personally i couldnt care less if Greer looks for faries in his back garden, alot of physicists are christians and believe in mircles and the power of jesus, does that make their work worthless? of course not.
