Dear CBS:

Here is an analogy that may help you understand why "The documents might be fake, but the substance is real" is an illegitimate argument.

Suppose I own a small, second-hand bookstore. Dan Rather walks in and
picks up a copy of Earth In The Balance. He comes
to the cash register and hands me an obviously counterfeit, forged check.

"I can't take this," I tell him. "It's both a fake and a
forgery."

"The check may well be both a fake and a forgery," Rather responds.
"But my producers and I are confident that the account it's written on contains
actual money."
