Sens. Jon Kyl and Pat Roberts said in a report that the answer to the question - could 9/11 have been prevented - is yes, if State Department personnel had merely followed the law and not granted non-immigrant visas to 15 of the 19 hijackers in Saudi Arabia." If laws had been followed, "most of the hijackers would not have been able to obtain visas and 9/11 would not have happened," they said. Both [senators] were part of the House and Senate intelligence committees' inquiry into intelligence failures leading up to the attacks. Last week, in its final report, the inquiry said agencies were poorly organized and failed to share information, but didn't identify a single intelligence error that, by itself, allowed the attacks to occur. Kyl and Roberts ... said the inquiry findings, most of which remain classified, didn't dig deeply enough into the cause of intelligence problems. They said also intelligence committee leaders excluded other lawmakers from key decisions during the investigation. Their report also said the investigation's scope, confined to intelligence issues, was too limited. The most glaring omission, they said, was the failure to examine State Department procedures for issuing visas.
