In the tradition of Swift's modest little proposal, I've got an idea. Now, follow me here:

1. There's a number of reporters (some reports say 6) who know who the "senior government official" is who dropped Valerie Plame's name, including Bob Novak, who was stupid enough to use it.
2. None of these reporters wants to reveal who that person is because, they fear, no one would ever leak to them again.
3. These reporters (with the exception of Novak, who's been trying to deny it ever happened since he wrote about it, which is kinda like saying, "you really can't trust what you read in my columns" without saying that directly) would really like the world to know who that leak is.
4. What's to stop one of these reporters calling up another reporter and leaking who the leaker is? The new reporter can protect his reporting source is, and no one really knows which of the six (or so) it is because it could be any one of them (with the exception of Novak, I guess).

Normally, this wouldn't work, because in a normal situation, a leaker with sensitive information (say, Deep Throat), calls one reporter (say, Bob Woodward), and these two have a mano-a-mano situation where the reporter gets the moolah and the leaker doesn't get burned by the people he's leaked about. But in the Plame Game, the leaker decided if one reporter was good, a half-a-dozen had to be better, so he (or she) scattered his (or her) seed to the wind (kind of begging the question about what the point of this leak was all about, you see).

Or, hey, you know, George W. could just call up Bob Novak and ask him, on the sly, who the leaker was, so that he could keep that dumbass out of any future National Security meetings. Of course, that would mean that Georgie was actually interested in resolving this crime, and not somehow involved in the first place.
