There is another possible explanation for Scooter Libby’s odd letter. Let’s suppose that when he talked to Miller he went close to the line – but not over it.

In other words, perhaps he knew that Plame worked at the CIA as an analyst but did not know – and did not tell Miller – that she was (or had been) a covert operative.

Or perhaps he did know about her covert work, but knew also that he couldn’t reveal it — and so was careful not to do so.

Nevertheless, could he be sure that after all this time and all that has been in print Miller would remember it that way?

I don’t think anyone would want to bet the next five years of his life on that.
