Cronkite was going on and on about how Adlai Stevenson was attacked by right-wingers in Dallas a few weeks before the assassination.
And all the commentary immediately afterwards was about how the Right Wingers were out of control, as if to imply they were behind the killing. They even did in the street interviews where people who insinuating that it had to be a Right Winger that shot Kennedy. They really weren’t going to let that crisis go to waste, if they had their way.
I am not an expert on the history of the American Media, but without a doubt, Cronkite was the first propagandist of the modern TV news era... he spawned a new character, ‘the well spoke, well-dressed news anchor who is simply reporting the facts’ that was prevailed until that model/psy-op imploded in in the last decade or so.
