Although I was not able to go to the lecture I did watch the entire speech at home. (It's a good thing that I cancelled my 1.30 class since it ran until 1.45) It was a good speech, he is by no means a wordsmith, but I feel that it can be overlooked. He presented a very good argument of why we need to be vigilant of terrorism; as a foundation of peace for the future, but I still am not sold on the necessity of some of the means to prevent the domestic terrorism (i.e. citizen surveillance).
Besides the Patriot Act issue I was impressed by not only his openness, but also his wide range of knowledge. After his speech he took questions from the audience ranging from the African Union to Tony Blair to Social Security. He was able to answer all the questions adequately with the only question not answered was: "What did you think of Broke Back Mountain"? To which he said he had not seen.
Overall the lecture was enjoyable and he seemed to enjoy giving the speech. I am glad that he came to K-State and I hope that we can continue to host very important people for the Landon Lecture Series. (Last fall Mikhail Gorbachev spoke at a Landon Lecture.)
I will post a link to a video of the Lecture when it is available. Video of Speech.
