I assume that the documents which have disappeared were ones taken on the first visit? After they suspected him, why would they give him originals? These people protect pretty important stuff so I wouldn't expect them to just be dumb.
OR maybe NOTHING has truly disappeared? Maybe there really are copies of everything and someone wants to give Clinton and Co a false sense of security? Wouldn't that be delicious?
On FNC tonight John Gibson said at the My Word segment that Fox contacted their sources (two) who confirmed that Berger was seen stuffing documents in his socks.
