More on the body language at the Obama presidential inaguration

The most remarkable aspect of the Obama's body language at the presidential inauguration was the lack of reaction to the enormous crowds on the mall. I know he was trying to be presidential I watched him take on the mantel of seriousness and change his facial expression to a down turned mouth as he came out for his swearing in, but why not react at all? Why make the entire speech so practiced and rehearsed that he couldn't even have one spontaneous smile or wide open eyes and raised eyebrows in awe at all the people who have put their trust in him? Why not reach out his hands or look directly out at them one time as he spoke?
What do you think?
