This is the norm the Bush administration, which likes to keep the president from being exposed to dissenting opinion. James Bovard told the story of retired steel worker, James Neel, who was arrested at a Bush event a couple of years ago while carrying a sign that read, "The Bush family must surely love the poor, they made so many of us." That case was thrown out of court:
At Neel’s trial, police detective John Ianachione testified that the Secret Service told local police to confine "people that were there making a statement pretty much against the president and his views" in a so-called free speech area. Paul Wolf, one of the top officials in the Allegheny County Police Department, told Salon that the Secret Service "come in and do a site survey, and say, 'Here’s a place where the people can be, and we'd like to have any protesters put in a place that is able to be secured.'" Pennsylvania district judge Shirley Rowe Trkula threw out the disorderly conduct charge against Neel, declaring, "I believe this is America. Whatever happened to ‘I don’t agree with you, but I’ll defend to the death your right to say it'?"
All the president's men shelter him from opposing viewpoints to avoid having him wind up like this other emperor:
So now the Emperor walked under his high canopy in the midst of the procession, through the streets of his capital; and all the people standing by, and those at the windows, cried out, "Oh! How beautiful are our Emperor's new clothes! What a magnificent train there is to the mantle; and how gracefully the scarf hangs!" in short, no one would allow that he could not see these much-admired clothes; because, in doing so, he would have declared himself either a simpleton or unfit for his office. Certainly, none of the Emperor's various suits, had ever made so great an impression, as these invisible ones.
"But the Emperor has nothing at all on!" said a little child.
"Listen to the voice of innocence!" exclaimed his father; and what the child had said was whispered from one to another.
"But he has nothing at all on!" at last cried out all the people. The Emperor was vexed, for he knew that the people were right; but he thought the procession must go on now! And the lords of the bedchamber took greater pains than ever, to appear holding up a train, although, in reality, there was no train to hold.
