Who would think to look in an unguarded garage for highly classified documents. I’m sure it woked very well.
There is a hitch. The proper thing to do at this time is to assume that they were all compromised. Moreover, there might have been secondary compromises. Every message that was transmitted with a code compromises the code; and thereby, any other message transmitted with that code.
Besides all that, who in their right mind stores highly classified documents in their garage?
Oh, yes. Mrs. Clinton did store her classified emails in a bathroom. That was a little odd, too.
