David Litchfield is such a respected authority in this field that many of us consider "Because David said so" to be the same as fact, and his mere opinion, offered to the list for free, is a gift to the security community.
Question everything, especially when it comes from an expert. The facts can stand up for themselves. Lets engage in science, not religeon.
(No disrespect intended to Litchfield).
