Finally, on the issue of military commissions and the evidence they might hear, Stephen Hadley was pretty forceful:

In terms of the military commissions issues, I’ll just give you a quick summary. A provision dealing with classified evidence makes sure that no sensitive intelligence will have to be shared with terrorists or their lawyers. The bar is very high. There will not be — the terrorists will not have access to classified information.
In addition, if classified information is required for the prosecution of a terrorist, there are a variety of ways in which the substance of the information can be provided and used at trial without transferring classified information. And of course, finally, under all circumstances, information about sources and methods, which is the most important, is protected.
