If he isn't lying, then do you support the CIA punishing him for someone other agent's mistake?

I didn't say I supported punishing him. I said "If" he did a certain thing, he would be guilty of mishandling classified information. If he didn't do that certain thing, then he's not guilty.

In the course of handling nearly 2000 documents, it would be easy to make a mistake and accidentally include one that had not been approved by his supervisor.

Going solely off of the information in the article, if he made no such mistakes, the fault should lie with his supervisor (If and only if it can be proven that his supervisor approved the release of information that he should have known was still sensitive.)

I was just talking about the handling of classified information in general. From the limited information we have, it seems like this particular CIA agent was just trying to do the right thing. I was just attempting to illustrate that when it comes to handling classified information, it is very easy to make an honest mistake that could land you in a world of trouble.

That's part of the reason I got away from working for the government. Too much stress.
