Obama/McCain pay homage at Ground Zero and how???

In the news today both the candidates went to ground zero to pay homage to 9/11 victims...I couldn't help but notice how Obama just threw a flower on the site and how McCain carefully placed it the way it is supposed to be.luckily I got a pic of the same and want to share with all of you.Do you think it was right of Obama to throw the flower(whether he meant it or not it looks disrespectful).your views please..hope its the right section to post.

Before, I address the actual question on hand. Is there an actual video showing Obama throwing the flower. Many times when placing flowers at memorials, instead of bending down to put it there people gently drop it from their hands. If there is a large pile of flowers people may try to get elevation so the flower does not slip down.
