I know this guy!

I've seen a speech of him in '06 at a fair. He is a cool guy and had some very interesting points, especially as he a former government member. The speech I listened to was about energy and about the war in iraq, I thought it was very informative.
Yes, the video gets somehow devaluated through the other events it shows, the 9/11 truth guys confronting Cheeney and the Paul protestors - can't see their point.
To be fair, what I've read about him today, he is not one of these 9/11-was-an-inside-job guys, he critizises the report, not the fact that planes went into the buildings.
Regarding the silent protest: in the few seconds before the camera zooms out, I could hear no other voice than Hillary's, but we can't tell from the vid what happened before.
