This Is A Minor Point

But we've made most of the major points. 9-11 Deniers like to make a big deal out of John Ashcroft's avoidance of commercial flights a few months prior to 9-11. The story arises in this article:

In response to inquiries from CBS News over why Ashcroft was traveling exclusively by leased jet aircraft instead of commercial airlines, the Justice Department cited what it called a "threat assessment" by the FBI, and said Ashcroft has been advised to travel only by private jet for the remainder of his term.

Let me ask an obvious question. If Ashcroft was in on the plot, wouldn't he have known which planes were going to be hijacked, or "hijacked" if you prefer? It's the same thing with the supposed call from Condoleezza Rice to Willie Brown; if you buy her complicity in the plot, wouldn't she have known that no flights leaving San Francisco were at risk?
