Good point.  But no, I don't think Cheney is that stupid, or even that crazy.  I think Occam's razor clearly points to stupid/crazy/desperate/pissed off people far far lower on the power pyramid.  People like two guys who were just arrested for plotting mayhem and assassinating Obama, or moving up a little higher on the pyramid, like the Taliban wannabes who kidnapped 2 Chinese engineers in Pakistan, or the gangsters who kidnapped a Pakistani oil worker in Somalia.

Truth unfolds in time through a communal process.
