The flying missile narrowly missed hitting the President yesterday.
It is not clear what the book was, where it came from in the crowd, or why it was thrown at Mr Obama - who did not appear to notice the danger.
Kind of like the shoe incident with Bush, but this was right here in the U.S. They haven't caught the person. It appears the Secret Service is slipping.
