The Behind the Bastards podcast did a good (3-part IIRC) series on MKUltra. Well worth a listen.
(My response to) Behind the Bastards reminds me of (my response to) the movie Fahrenheit 9/11. While I emphatically agree with his POV, Michael Moore's creative voice makes me cringe. Worse, I feel that Fahrenheit 9/11 is the coloring book version of the Bush Admin's crimes and misdemeanors.
However. After watching the audience's reaction, I accept that Moore is right and I am wrong. He met people where they're at and showed them something new. Resulting in a greater awareness. I certainly could not have done that.
Given Behind the Bastard's popularity, I know that Robert Evans and friends are doing the same yeoman's work. Which I appreciate and respect very much.
