I don't really care what classified documents Hillary was emailing with other members of our own government. Yes, I realize that there is a massive risk that foreign governments could have intercepted them. I acknowledge that is a huge risk.
Hillary has repeated several times that all of her emails with the state department, etc are properly documented and could be subject to FOIA requests. This is technically correct, we could get copies of any emails sent to/from Hillary Clinton and other members of our government.
What really concerns me, that I see nobody talking about is: we have no clue and no record that we can trust that documents Hillary Clinton's communications with governments not our own. What were the communications with the head of the State Department was having with Russia, China, Iran, etc? I understand that a great many of these communications may be "classified" or otherwise sensitive and not something for general public consumption today. But we will *never* be able to FOIA such documents 25, 50 or 100 years from now. Our inability to re-construct the details of historical events in the future has been greatly damaged.
The simple fact that even our own president can't say "get me every damn email that Clinton has sent to Russia" should be worrying to everybody.
