One homeland security official says it would be dangerous to think we're safe just because the nation got through the election without a terrorist strike. Officials remain concerned about the upcoming holidays, the January 20th presidential inauguration and beyond. Counterterrorism experts are analyzing why al-Qaida may not have attacked and what may be ahead. They've been combing through two tapes released by al-Qaida in the two weeks before the election -- the first featuring a man calling himself "Azzam the American," the other, Osama bin Laden. One consultant to the government says he's concerned about an attack directly against US interests now because the new tapes represent "the most significant effort by al-Qaida to address the American people in the last couple years."
