Additionally, every copy which is classified "Secret" or above is always numbered and tracked. It's the law and everyone who handles these documents knows what they are......copy or orginal. Sandy Berger knew precisely what he was stealing and what the law says about it.
The only motive I can discern is that he must have believed he had originals(drafts submitted for review)........very few in number......and he got them all. Perhaps to ensure his chances of a good job in a prospective Kerry adminstration???
Thanks!
