Whistle blowers like Gary McKinnon, Phil Schneider, Charlie and Julian Assange have told the world about some aspect of reality that appears to be hidden for obscure purposes. Gary McKinnon for instancewas said to have uncovered a list of non-terrestrial officers, which suggests that the united states has ships in space! But the story is somewhat unclear, as McKinnon later countered some claims about the case made by others.
But think about the conundrum of whistle blowers: why would they be persecuted if what they are telling people about is not true? On the other hand there are sites like WikiLeaks which have published lots of leaked documents, and let the users form their own assessment.
