"And in that we spirit -- in that spirit we should acknowledge that on Christmas Day, the system did not work. Abdul Mutallab passed through airport security with a bomb, and he boarded a flight hell-bent on killing innocent passengers. This terrorist trained in Yemen with Al Qaida, his American visa was not revoked until after he tried to kill hundreds of passengers. On Christmas Day, the only thing that stopped this terrorist was blind luck and brave passengers. Really, it was a Christmas miracle, and that is not the way that the system is supposed to work."

Sarah Palin comments on the Christmas Day attack that could have happened.
