Americans aren't the only ones frustrated by the lack of news on terrorism attacks thwarted by Uncle Sam. The FBI feels it too--yet realizes it can't brag on all its success. But FBI Director Robert Mueller offers us some reasons there haven't been any sensational hits: Terrorists don't have many places to train anymore; cooperation between governments is stronger; intelligence is better; and many of the bad guys have been captured. "I think we've become safer," he says. But beware. He says al Qaeda attackers are still here, most likely "waiting for the opportune moment."
