I think the best part about this is he is not completely willing to say that the U.S. should or should not be doing what it is doing per se, just that it should not be doing it without the consent of the governed. He wants us to ask where the line should be drawn as a people, and his basic concern is that we are not being informed, not that the wiretapping is happening. This shows a profound respect for democracy and the country, since he seems to have faith that if all the facts are laid bare our country will do the right thing.
