White House blames "the media" for brouhaha over unannounced terrorist attack exercise this morning on the Potomac

It's well known that local media, at the very least, listen to police scanners. This explanation does not suffice. The police scanners said that there were terrorists on the Potomac near the Pentagon while the president was speaking on 9/11. That kind of chatter would obviously cause a panic. The media makes a lot of mistakes, this is not one of them.
