Because of this, I infer / assume she likely did... That, or the line on what is top secret / classified is not always obvious.
I believe it is far more likely that she didn't know the information was classified because it may not be obvious that is was classified.
Extrapolating from how we are required by the government to handle technical information at work, simply quoting a line from a controlled document in an e-mail makes can make that e-mail controlled, too--even if the information may be publically available (as on the internet). Assuming that a similar rule applies to secret documents, it would be trivially easy to put in a line from a secret document in an e-mail, making the entire e-mail "secret." Thus the requirement to label such e-mails "secret" by the sender.
Now just imagine that you are a government official who receives dozens of e-mails a day. Would you expect that you'd be able to recognize a line that contains information from a secret document? Would you expect
anyone to be able to recognize it from the hundreds of classified documents that exist, including ones the person is not familiar with?
Of course, some information is obviously classified, or something that Hillary could have recognized. The devil is in the details. But just because information is classified doesn't mean it is obvious. It could look innocuous, and only after careful analysis would it be revealed to be classified.

Alas, Lloyd, the WSJ opinion piece appears to require a subscription. Do you have a cheaper source?
