Oh, they know something 'aint right, and they know that the official stories with the motives given are bullshit.  They just haven't figured it out.  Most of them think it's simply unbelievable (all the MK Ultra stuff).    And I think there are some who know deep in the recesses of their minds it's true, but then admitting it is scary, particularly because there's nothing any one of us can really do about it to stop it at the root.  That's a job reserved exclusively for whitehats in government.
