Actually, no, the guy’s aim is right on; Bush just works fast to get out of the way.
Hate to be an armchair critic, but I think the trick is to allow for the movement, and aim lower. In my heart of hearts, though, I just don’t see the opportunity arising again. Oh, God, if only the guy had thrown it while Bush was looking at Al-Maliki! Why couldn’t that have happened? The sound alone would have almost made up for the last eight years!
