I think the Saudis thought they can leave the country and not be held accountable VIA diplomatic immunity and Condit would fade into retirement once he got his pension (6-9 months?) quit Congress and slip out of the country quietly.
Now there is this messly little matter of the accusations of a sitting Governor of a populous state and a former Presidential candidate/ former Congressman who were in on the deal as well.
But no one knows what those 'Gentlemen' saw, or if they just participated in the coverup.
