I remember in college taking a class on things like this. They showed that you can tell the story of a President doing something bad, but show him with balloons being released and crowds cheering him as you tell the story, and people will remember what they saw not what they heard. Which is true, because I remember the balloons going off and the President smiling and waving, but I don't remember what the bad story was.
So this picture wasn't an accident. They are telling a story people will forget the words but not the images to.
