Appreciate your confirming what I said. You have no idea. This is why they coined the phrase, "talking heads". News people read copy. Improv is not what they do.
Dear Sonderführer Storing,
Your boy, out-of-breath Dan Rather, wasn't "reading copy," he was "winging it" and trying to remember what he thought he'd seen during his one noteless viewing of Zapruder's confusing clip.
D'oh!
