How about the two Saudis in San Diego watched by two FBI agents who tried to warn the authorities in Washington? We might carry it a little further to Prince Bandar's little princess that paid their expenses. An explanation might be offered as to how the Bin Laden family and some of their Saudi friends were flown out of the country immediately following 9/11 when the rest of commercial aviation was grounded for two days. The hearing was just window dressing so the public would be diverted from other questions that need answered.
If anything was accomplished other than trying to shift the blame game, it was a good demonstration on how ineffective our bureaucracy can be expected to be on domestic security. Both administrations have failed to come up with solutions to our security problems because our government is so large and unwieldy. As long we insist on all roads leading to Washington in a centralized setting, we are vulnerable.
