Nathan Hamm was present when Hamid Karzai received the Liberty Medal in Philadelphia. He has an excellent account of the event in The Argus:
"As many of you know, I went to see Hamid Karzai receive the Philadelphia Liberty Medal at Independence Hall yesterday.
It was absolutely beautiful in Philadelphia yesterday and far from crowded in the city in the morning. The area around Independence Hall was entirely blocked to traffic and crawling with uniformed and plainclothes police and a healthy dose of Secret Service agents."
