Sandy Bergerer--What did he steal and why?

[MS Fowler]

The Inspector General's report on Berger's "incident" at the archives indicates that his theft was willful. Some of the documents had never been catalogued, or copied.
Since the 9-11 Commission Report assumed that they had all the information, and now it appears that at least some of the information has been destroyed, does that bother you? Remember, Colson ( Nixon/Watergate) served time in Federal Penitenary for merely LOOKING at 2 confidential files. Berger stole and destoyed Classified documents. Is this justice?
Since Berger was poorly proscecuted and already penalized--a fine and loss of clearance for a while, he cannot be charged as that would be double jepordy. ( Shouldn't someone who destroys Classified documents lose his clearance for life at the very least?) However, his plea aggrement included a provision for future testimony and lie dectector test. Wouldn't it be prudent to attempt to discover the truth?

What did he steal and destroy, and Why?

His motive would seem to be to alter the historical record to protect either himself, or his old boss, Bill C. What other possible motive could there be?

So again I ask, What did he destroy, and why?
