It is clear Berger knowingly took classified information. It is reasonably clear that he took it on the behest of the Clintons . The question now is, what exactly did he take? If the documents have been destroyed it becomes difficult to ascertain. The only hope then being Berger cutting a deal to save himself. Once 'what' is known, 'why' should be clear.
I don't think this hurts Kerry directly, but indirectly, by overshadowing his campaign and causing dissension in the party, it could be a fatal.
IMO
I have not had time to read the thread today yet, but Bergler by nature of his job had to know they were copies, and the originals would remain. So why do it? I will update myself on this thread about 10 PM to see what is known at this time. I still dont get it.
