Yes. But the next question to ask is WHY? Could it be that these Saudi operatives were working by order of the royal family, and that the royal family was working with Bush/Cheney to intentionally do this -- as a favor? The cover up, I'm speculating now, is to maintain good relations with Saudi Arabia, because we have such a mutual dependency in terms of buyer/seller of oil. If the FBI established the royals were involed, they have hit a brick well and everything beyond that point is above the FBI pay grade.
