She's been very careful to say "marked
classified". That leaves a very big hole of "Well this information SHOULD have been MARKED classified, but wasn't." That leaves a gaping hole where she could have read a bunch of classified documents, talked about shit IN those documents all day in emails she generated, but she never sent the actual documents where she learned that information. Information is marked classified by a classification authority, which it doesn't sound like she is.
It's the difference been discussing the secret laser death satellite program in a Starbucks and leaving the documents describing that program there. Some of those conversations should not have taken place on the open internet, whether it was a private E-Mail server or one of Google's.
Not that most people would understand the distinction unless they've been forced to sit through the classified documents handling training, which you HAVE to re-do every so often. So it very much still makes what she's saying pretty fucking weasely. I mean even if it didn't sound pretty fucking weasely if you've had to sit through that training. It sounds weasely to me because I know all the shit she's excluding and I can hear her have to remind herself to say those specific words, "*marked* classified," so she can claim she didn't lie whenever someone finds classified information on there. And she sounds weasely to regular people on the street because they don't understand the distinction between "marked classified" and "sensitive information that really should be marked classified."
