until we know more - until they start naming the names of the people who destroyed Shaffer's document store (if that indeed happened) - saying Rumsfeld was involved in the "cover-up" is a big stretch.
"naming the names of the people who destroyed Shaffer's document store (if that indeed happened)"
Not only did it definately happen, but the name of the person who did it is publically well known and the person has made statements to the media. What is not yet clear is who initiated the order.
