As sad as it is, I think a way to reach those LIV that actually care about the truth is to make a movie along the lines of Zero Dark Thirty with all of the explosions and drama and the actual facts.
Re the movie on Benghazi....
I keep hoping that Clint Eastwood (or other conservative Hollywood folks) is/are working on such a movie. I do think they probably need more facts, but I do hope a screenplay is in progress.
