On average, since 9/11, the FBI reckons that just over 100,000 terrorism leads each year have come over the transom. Analysts and agents designate them as immediate, priority or routine, but the bureau says every one is covered.
Most people inside the bureau believe that the blown opportunities to head off 9/11 would not recur today. Even among the FBI's doubters, few disagree that the bureau has come a long way.
