I figured Sandy was trying to hide something that made them look like worthless wimps, but was considered unimportant at the time. Otherwise they had plenty of time to destroy it like all the other incriminating stuff they routinely deleted. It only shows how criminally arrogant they are by trying to pull off a stunt like this under W's watch.
I sure wouldn't want to be the guy who prosecutes Burglar. The media will destroy him.
BTW, Where was that particular archive building located? If he is tried in DC, there will be an O.J. jury to acquit him.
